     Somewhere on the Eastern Front, a kradmelder (dispatch rider) for the regimental headquarters (Regimentsstab) of Artillerie-Regiment 110 prepares to get under way. Of all the belligerents during World War Two, the German military was the largest user of both motorcycles as well as dispatch riders. These men played a critical role in delivering urgent orders and messages between headquarters and units out in the field. Often, this was because wire communications between units and their headquarters was either not yet in place, the distance too far to establish such communication, time was not available to set up wire lines, or the wire lines run had been broken, sabotaged, or in some way destroyed thus severing such communication channels. Typically, dispatches were sent back and forth by foot when moving messages between züge (platoons) and kompanie (companies) but when communicating to bataillone (battalions) and higher units, the kradmelder was utilized. Obviously, the job of a kradmelder, or any dispatch rider regardless of nation, was a dangerous one as they often operated alone. Even moving behind friendly lines, front depending, was no guarantee of safety. Each kradmelder was trained to maintain his motorcycle and spare parts were often carried so that any common mechanical failure could be corrected in the field.

     The Germans issued the kradmelder, and other users of motorcycles, a unique piece of protective clothing which was called the Schutzmantel für Kraft Radfaher which translates as Protective Coat for Motorcyclists. The double-breasted coat was rubberized so that it was waterproof and it also fit loosely. The coat also featured a wool faced collar, split tail, and four large pockets (two on the front, one on each side) with button-closure flaps. Each tail could be gathered around the rider's leg and buttoned into place. This made for a more snug fit and thus made the coat less awkward to wear when sitting on the motorcycle and also lessened the chances the coat material might catch on objects, to include the motorcycle's own rear tire. The coat was standard for both enlisted men as well as officers who operated motorcycles. The rider in the photograph has wrapped the coats' tails around his legs and the bottom of one of the front pockets can just be seen beneath his arm. The clear shield he is using to protect his face is not often seen in photographs with the usual protective equipment being a pair of goggles and conditions depending, a scarf or piece of cloth to cover the mouth and nose. In cold weather, some kradmelder used their gas masks, without the filter, to protect their face from the frigid temperatures. Other equipment visible includes the cylindrical gasmaskenbüche (gas mask case) and the square, rubberized pouch for the gaskap (gas cape). Strapped to his back is a Mauser 7.92mm k98 bolt-action rifle.

     The motorcycle he is riding is a DKW (DampfKraftWagen) NZ 350. By the time this photograph was taken, DKW was building the NZ 350 exclusively for the Wehrmacht. The motorcycle was powered by a 1-cylinder, 2-stroke, air-cooled 346cc engine which developed approximately 12hp. This was paired with a 4-speed transmission. Top speed of the NZ 350 was 65mph. Fuel capacity came from a 3.6 gallon fuel tank with the engine consuming, under normal operating conditions, almost one gallon of gasoline every 62 miles. Of interest, however, is that the license plate affixed to the top of the front fender is not military but a civilian plate. This is because all Wehrmacht military plates started with WH (Wehrmacht Heer for the Army), WL (Wehrmacht Luftwaffe for the Air Force), WM (Wehrmacht Kriegsmarine for the Navy), or SS for Waffen-SS license plates. The “M” on the plate is the Roman numeral that corresponded to a German city or district in which the motorcycle had been registered. The circular red object is the registration proof of issue by the local police. The upper portion read “Der Polizeiprälident” (Chief of Police) and below it would be the city name. It was not uncommon that civilian owned motorcycles were impressed into German military service given that demand for them was high.

     Finally, when this photograph was taken, the regimental headquarters staff for Artillerie-Regiment 110 had been attached to the I. Armeekorps (1st. Army Corps), 18. Armee (18th. Army) which was a part of Heeresgruppe Nord (Army Group North) during the invasion of Russia that commenced on June 22, 1941 with the launch of Unternehmen Barbarossa or Operation Barbarossa. By October 1941, it was subordinated to L. Armeekorps on several occasions. By the close of 1944, the unit was the 17. Armee and by the spring of 1945, it was under 1. Panzerarmee, LIX. Armeekorps in Silesia. As for the remainder of the unit, I.Abteilung (which encompassed three batteries) was assigned to Artillerie-Regiment 74 in 1939 and III.Abteilung (also three batteries) joined Artillerie-Regiment 74 on July 29, 1940. Artillerie-Regiment 110 was designated a heavy artillery regiment which meant it was equipped with 150mm or 170mm caliber guns.

Russo-Ukrainian War: The Skybike CRDX-200

     The usage of motorcycles in war is nothing new. In fact, they saw widespread use starting in World War One where motorcycles were used primarily by reconnaissance units for scouting but also served a more vital role as the mainstay of communication units where dispatch riders found the motorcycle indispensable as a means to relay documents and orders between units when radio links were not available. To a lesser extent, motorcycles were used as transport for personnel and supplies. More recently, special forces around the world have adopted motorcycles as they are easily airdropped, small, and provide rapid off-road movement. The advent of viable electric motorcycles able to handle the rigors of the battlefield have added an element of stealth for special forces operators who no longer have to worry about the obvious engine noise of conventional petrol powered motorcycles.

     However, what was quickly learned was that motorcycles have little place in assaults. It was tried in World War One and the outcome was a disaster and the concept quickly abandoned, never to return. That was until the Russo-Ukrainian War, which started in late February 2022. The Russian Federation, in response to high losses of armored vehicles and logistical vehicles, has seen units more and more fill out their ranks with ATVs, civilian cars and trucks, and motorcycles. While it would be within reason that such vehicles can work well enough behind the lines, Russian units use them on the front lines. Notably, motorcycles are used in direct assaults against Ukrainian lines. 

     The Russian logic for “assault motorcycles” on paper seems somewhat reasonable. Motorcycles are fast, permitting the infantrymen riding them to rapidly close with the enemy. Once near, they dismount and fight on foot. Second, motorcycles are not heavy enough to set off landmines designed to target far weightier armored personnel carriers. Third, motorcycles are more maneuverable in comparison to bigger and slower armored vehicles which makes the job of FPV drone operators a bit more difficult. Combine the latter with man-portable drone jammers, that job gets a little harder.

     But, the disadvantages of using motorcycles in the assault are pretty plain to see. Motorcycles are not armored nor do they offer the rider any measure of protection against bullets or artillery/rocket fragments. Secondly, the rider cannot deploy his weapon with anything close to usefulness. At least one hand needs to steer the motorcycle and being accurate while “one-handing” an AK-74 is pretty laughable. Third, the rider has to divide his attention between the enemy and the terrain, especially when “off-roading” lest he run into a shell hole or hit an obstacle. To be fair, a lot of Ukrainian terrain is relatively flat with low grass in areas where cropland is not able to be planted. Finally, Ukrainian FPV drone operators are more than capable of hitting a Russian motorcyclist at speed and drone jammers are absolutely no guarantee of safety. That is because there is no way of knowing if a particular drone running down a motorcycle is using a frequency that rider's EW (Electronic Warfare) device is capable of jamming. Needless to say, the Russian Federation is finding out what other countries learned a while ago...motorcycles in the assault does not produce worthwhile results. But that hasn't stopped the Russian Army and so losses are very high with motorcycle troops having quite a short lifespan.

     The Ukrainian Armed Forces, notably the Ukrainian Army and Ukrainian Special Forces, do utilize motorcycles. Besides being used for the age-old roles of dispatch and scouting, they are also used by logistical units to quickly run supplies to front-line troops. They are not used for assaulting Russian lines. The particular motorcycle seen here, used by a soldier (drone jammer on his back) of the 58th. Motorized Bridgade “Ivan Vyhovskyi”, is a Skybike CRDX-200. Skybike is a brand name held by the Chinese company Sky Team, Ltd. which is a manufacturer and exporter of motorcycles. The CRDX-200 has a retail cost of around $1,500USD.

     Power comes from a 1-cylinder, air-cooled, 4-stroke 197cc engine that develops 14.3 horsepower. It is paired to a mechanical, 5-speed transmission. The engine is provided with both electric start as well as the more standard mechanical kick starter. Maximum speed is 71 miles per hour. The fuel tank capacity is 1.5 gallons. The CRDX-200 uses front and rear disk brakes while for suspension, the front utilizes inverted telescopic forks while the rear is a pendulum-style monoshock absorber. Thanks to a lightweight steel tubular frame, impact-resistant plastic components, carbon alloy exhaust pipe, and light alloy front forks, the CRDX-200 weighs 220 pounds.

The Soviet 37mm ChK-M1 Anti-Tank Gun: Sidecar Armament Extreme

     Prior to World War One, the motorcycle was starting to be seen as a viable replacement for bicycles. The Germans were the first to introduce the motorcycle into military service in 1904 and by 1914, both the British and the United States also had motorcycles as part of their military forces. Not surprisingly, the usage of motorcycles continued through the post-WW1 years and when World War Two began, all of the major warring powers utilized motorcycles of various makes. Motorcycles were used by couriers, messengers, and as transports for men and matériel but the largest use of motorcycles was by scouts conducting reconnaissance operations. Not too surprisingly, sidecars were often attached to motorcycles. This permitted the motorcycle to carry a passenger, cargo, and in some cases, used to carry wounded away from the front line. As a vehicle used by the military, sidecar equipped motorcycles were soon fitted with weapons, even as far back as World War One. German Zündapp KS 600 and BMW R12 motorcycles with their sidecars fitted with Maschinengewehr 34 machine-guns are a common image in many books on World War Two. There were attempts to equip sidecars with heavier weapons and perhaps the Russians can take the grand prize for the largest gun ever fitted to a motorcycle/sidecar combination.

     Prior to the 1930s, the Soviet Union did not have much in the way of indigenous motorcycles and relied heavily on imports. In fact, during World War One and into the Russian Civil War, the major brands of motorcycles in use by the Russian military were Indian and Harley-Davidson. By the mid-1930s, the Soviets were well on the path to producing their own motorcycles such as the TIZ-AM-600 (a copy of the British BSA Sloper 600), the PMZ-A-750, and the Dnepr M-72 (copy of the BMW R71). Still, Harley-Davidson motorcycles continued to see use and during World War Two, the Soviets received over 30,000 Harley-Davidson WLA motorcycles via Lend-Lease. So, a Harley-Davidson motorcycle was selected for the testing of a sidecar mounted ChK-M1 37mm anti-tank gun as a means of moving the gun around the battlefield. As a side note, the gun was also fitted to Lend-Lease Willys MB Jeeps and the GAZ-67 (the Soviet equivalent to the Jeep) among other transports.

     The ChK-M1 was the final result of development of the ChKSh-1 which appeared in prototype form in the summer of 1941. The intent was to produce a anti-tank gun that could be airdropped and provide airborne troops with some capability to tackle enemy armor. Testing showed that the gun was flawed. It was deemed overly complex, had a slow rate of fire (between 8 to 10 rounds per minute), was inaccurate, and the armor penetration of the 37mm round was found wanting. In 1942, the Soviets set up a special design bureau, OKBL-46, to continue development of the ChKSh-1 and two designs emerged, the ChK-M1 and the ZIV-2. Between April 18, 1943 and May 28, 1943, both guns were put to the test but it was the ZIV-2 that came out the loser and the ChK-M1 was ordered into production on June 14, 1944. The first examples started to enter service in July 1944 and production continued through June 1945 with some 472 guns being produced.

     The ChK-M1 had several features designed to both lighten the weight (in keeping with the need to be airdropped) and limit both size and recoil. The gun barrel was surrounded by a cylindrical shroud and within the shroud was a inert mass and a recoil spring. When the gun was fired, the barrel recoiled a maximum of 3.9 inches and the inert mass disengaged from the barrel, moving backwards 3.5 feet, compressing the recoil spring which then moved the gun back into battery. The entire gun, excluding the muzzle brake, was 7.6 feet long. The muzzle brake also added to the reduction of the rearward recoil. A good crew was able to put 15 to 25 rounds through the gun. The ChK-M1 fired the BR-167 armor-piercing round which weighed 1.7 pounds (7 ounces being the charge weight) and the penetration was approximately 20mm at a 60 degree slope and 25mm at a 90 degree angle from 500 meters. The other round the ChK-M1 fired was a high-explosive round, the OR-167. The 1.6 pound round had a 7 ounce explosive warhead fitted with a MG-8 fuze.

     Some question if the ChK-M1 was actually able to be fired from the sidecar. The answer to that is that yes, it could, if the crew had no option to dismount the gun. The photograph makes it appear as if the gunner is resting the breech on his shoulder but he is not. When the gun recoiled, the breech would move to the right of the gunner's shoulder. The man seated behind the driver was the loader and both he and the driver carried ammunition in backpacks so in action, he would pull rounds from the driver's pack to hand to the gunner or load the gun himself. The ChK-M1 was fired via a trigger, which can be seen in the gunner's right hand. His left hand was used to effect traverse and what little elevation and depression the gun had via a vertical grip offset to the left of the breech. The far more normal operation of the ChK-M1 was for the crew to dismount it from the motorcycle, assemble the carriage, and deploy it in the ground role. A skilled crew could do this in 80 seconds. To that end, behind the loader were the simple, all-metal spoked wheels and carriage legs while the gun shield can be seen secured to the side of the sidecar. The gun shield was not large and had a meager 4.5mm of armor thickness which was, at best, proof against some small arms and fragments. The gunner was provided with a periscopic sight which allowed him to keep his head low and behind the gun shield. The entire gun carriage was very low and provided only 5 degrees of elevation and at most, 5 degrees of depression. The carriage also provided 45 total degrees of traverse. The low profile of the weapon usually forced the crew to operate the gun from the sitting or prone position. A typical ChK-M1 team consisted of six men and two motorcycles. The motorcycle shown here included the driver, gunner, and loader while the second motorcycle was manned by the driver, the gun team commander, and a ammunition bearer.

     The ChK-M1 had a total weight of 478 pounds and it could be carried easily within the two major Russian airborne troop gliders; the Antonov A-7 and Gribovsky G-11. It could also be carried by the Lisunov Li-2 (the Soviet copy of the Douglas DC-3). The gun was usually airdropped via parachute from the Ilyushin Il-4 but the Li-2 was also used for airdrops as well. The sole user of the ChK-M1 was the 98th. Guards Infantry Division, its personnel from the 13th. Guards Airborne Division that had been formed on December 20, 1943. On January 19, 1944, the unit was included within the 37th. Guards Airborne Corps until reorganized again December 18, 1944 to the 103rd. Guards Rifle Division. The unit never saw combat during World War Two. On June 7, 1946, the unit became the 103rd. Guards Airborne Division and reformed on October 15, 1948 after absorbing several other units. Finally, on April 25, 1955, the unit was disbanded. It was likely just as well that the division did not see action as the ChK-M1 was not well liked in service. It was found that the barrel rapidly wore out while the accuracy of the BR-167 round dropped off quickly. In addition, the penetration value of the round was, by 1944 and into the early post-war period woefully inadequate in comparison to the later war Soviet 45mm anti-tank guns (such as the 45mm M-42). Finally, crews complained that the simple sight of the ChK-M1 suffered in low-light conditions, something that also plagued the 45mm guns but rather than improve the ChK-M1, the 45mm guns were recommended to be improved upon rather than a light gun that had little value.
