German WW1 Vehicle
c5,000 built
For this first portal page on the great war, here is one that is a bit better deocumented thanks to the German Army administrative precision.
The German Imperial Army was the largest user and manufacturer of military trucks among the central Empires, thanks to its larger industrialization, world's second after Britain. Most brands were born even before Kaiser Wilhelm II came to power: Mercedes, Krupp and Daimler, Bussing, Opel. Others disappeared like Podeus. They provided all the trucks necessary to the German war effort, from road-only models to off-road models, but also staff cars, and artillery tractors. It's always surprising to consider than the Sturmanzerwagen A7V, the one and only German tank, had more unarmoured versions made with the same chassis, like the Flakpanzer and überlandwagen, the latter an utility tractor for the no-man's land.
Foreword
Motorisation in the Imperial German Army started as far back as 1899, when the first truck and first passenger car with internal combustion engine were tested for military use. The development really took off from 1908 with comparative trial runs held to find a vehicle in the role of Armeelastzug (truck-trailer combination). In 1914, a single truck model was given the role of supplier for all troops and on all frontlines.
However the state soon forced civilian manufacturers to join the effort and soon, Lastkraftwagen (cargo truck) diversity was ramped up, as more models came out, to become the backbone of German military supply operations in World War One. Soon also there was an administrative and organisational aspects with the creation of the Kraftfahrtruppe (Army Motor Transport Corps). During th ewar, if well-known Benz, Daimler and Opel took the limlight, other truck manufacturers joined the fray such as Büssing, Horch, Mannesmann-Mulag and Stoewer, or even more confidential such as Ageka, Komnick and Windhoff among others.

Operations

Motor transport columns in 1914 (Etappen-Kraftwagenkolonnen) comprised on average of 17 standard army trucks (Armee-Lastzüge) with trailers. Load capacity was already four metric plus the trailers (two tons) so that each column carried a total of 102 tons, which was almost twice the capacity of heavy horse-drawn columns (62 wagons).
Nine trucks represented 54 tons, but they moved at an average of 30 kilometers per hour for a range, loaded, of just 100 kilometers before reefill with gasoline. So these were done the closest to a railway as possible. But this was a heavy system, lacking flexibility and predictibl by entente powers that could plan and artillery bombardment on the approaching columns to the frontline. "Etappen-Inspektionen" were created as light motor transport columns (leichte Etappen-Kraftwagenkolonnen) for more flexibility. They comprised 15 trucks, each of three metric tons capacity and without trailers for better speed and mobility, carrying 45 tons total, and also modelled after those of the cavalry divisions. They were designed for speed first and foremost and could be used in a les predictible way as emergency commands, at divisional or corps level.
During the Belgian campaigns, these became paramounts to compensate the destruction of the railway system. It was also true for northern France and all had been already setup in prewar logistic planning for a westrn offensive. needless to say, these columns were even more vital in the east. By 1914, only 9,639 trucks were registered in Germany, almost all in civilan service. There were few standards, even less army trucks. The government subsidized private owners to purchase military-grade vehicle on exact specifications and have them ready for mobilization in 1912-13.
Civilian trucks were also requisitioned with the mobilization and a balance was chosen between transportation shortages of the army and the needs of the civilian society, not to disrupt trade supply. Percentages of available trucks were sized depdending on local avalability and use not to create much troubles. Later a plan was estabish to calculate further requisitions and constructions, based upon the number of all mobilized motor transport formations, estimations reached 2,000 trucks. They were all requisitioned for a grand total of 4,000 motor vehicles (inc. cars, tractors and light lorries) together with 8,000 drivers and mechanics to operate and maintain them. Many passenger cars were mobilized for the general staff and for laison along the front.
The German Volunteer Automobile Corps (Deutsches Freiwilliges Automobil-Corps) founded in 1904 under Prinz Heinrich v. Preußen, brother of the Kaiser also was activated and fully supported the mobilization and enabled a quantity far larger than planned prewar. So, in the end, just like a very efficient use of trained and railways, the road-bound logistic train of the Imperial German Army was really efficient, especially when compared to the French.
Staff Cars

Mercedes (1915), belonging to the Imperial Volunteer Automobile Corps (Kaiserlichen-Freiwilligen-Automobil-Corps), operating within the Empire's territory, were authorized to display registration plates with numbers painted in red. They were further identified by a special sign affixed adjacent to the rear registration plate. This sign took the form of a red square plate measuring 12 x 12 cm, with a yellow square placed in the center bearing the letters "K.F.A.C." in each of the four corners. K.F.A.C. vehicles operating in the rear sectors of the frontline were painted green-grey (Feldgrau) and marked with two broad crimson stripes on the body and hood/bonnet.
In 1916, this corps was renamed the Imperial Automobile Corps (K.Kf.K, Kaiserliches Kraftfahr-Korps), which may have influenced the marking system, although the specifics of such changes remain unknown. The Staff car of Admiral Ludwig von Schroder, Marine Korps, Flanders 1917, marked with its distinctive emblem featuring two crossed anchors topped with a crown and flanked by two flowing sashes. This symbol, originally embroidered on the shoulder straps of naval infantry soldiers since the early 20th century, became widely used after the outbreak of war. Painted on a white shield, it was displayed on both sides of the vehicle, on the doors of staff cars, and on the loading platforms of lorries.
Note: The vehicles are represented at 1:72 scale, except if specs are unknown.
Trucks


An early heavy lorry Podeus LIII with trailer (road train), produced for the Imperial Army under the Ministry of War’s subsidy program. During 1914–1915, these vehicles delivered supplies to positions no closer than 10 kilometers from the front lines, making the application of disruptive camouflage unnecessary.

The late-war (1918) Krupp-Daimler K.D.I heavy vehicle served both as a heavy artillery tractor and an ammunition transporter operating near the front lines. Although not typically exposed to direct enemy fire, these vehicles required camouflage to reduce the risk of aerial attack.

Note the unit designator (Formationszeichen) painted on the bonnet used by the Imperial Army between February 1915 and August 1917.
A7V Überlandwagen

The situation in 1915 – 1916 was dire, as Germany, Britain and France had settled into a stalemate. In order to solve the ‘bloody equation’ formed by the artillery-barbed wire-machine gun combination, both Britain and France began development on a vehicle that had the ability to cross trenches with ease and be able to withstand enemy machine gun fire. This tracked vehicle would eventually revolutionise the battlefield. Thus the tank was born.
Although the tanks suffered from mechanical failures and inadequate crew training they had a major physiological impact on the German soldiers. German intelligence subsequently submitted reports to the Oberste Heeresleitung (German supreme command or OHL for short), which then lobbied the war ministry for an equivalent. However, some of the senior officers of the time were more focused on artillery and infantry tactics rather than the development of the tank or similar armored vehicles.

A7V Flakpanzer

In WW1, the Germans used the A7V chassis as a starting point to develop several other variations. Although most would be used for the A7V Überlandwagen rough terrain tracked supply vehicle, others were used to create unique vehicles, such as a trench digging machine and the anti-aircraft version known as the A7V Flakpanzer.
Plans were also made to produce an A7V Funkpanzer wireless communication tank fitted with a Graben-Funkstation 16 radio transmitter and large circling antenna on the roof.
In order to combat the ever more numerous amounts of aircraft in the skies, German Army needed something that could fend off the enemy aviators, but also be able to relocate to a more defensible position if necessary. Little is known about this mysterious A7V Flakpanzer save for a few photographs. Three prototypes were being trialed in the closing stages of World War One.

Armoured Cars
If Germany lacked tanks, it had more armoured cars, from the same truck manufacturers. The Ehrhardt E-V/4 (Straßenpanzerwagen) was the Most important German armored car of WWI arguably, built in 1915, Typically armed with 2–3 machine guns and protected by 6–9 mm armour for a crew of 8–9 men and top speed of 40 km/h on roads. It had a fully enclosed armored body, unusual for the time, multiple firing ports and a rotating turret and were designed mainly for road use, not rough terrain.
Thy were deployed primarily on the Eastern Front, where open terrain and roads made them more useful and also used for internal security and anti-partisan duties.
The other important model was the Büssing A5P, much larger and heavier than the Ehrhardt with up to eight Machine guns and 10+ crew, this was a behemoth with versions in all-wheel drive, quite advanced for the time. It was however used on roads whenever possible and produced in smaller numbers. In general these models were unable to cope with the Western Front conditions (trenches, mud, shell craters) making wheeled vehicles ineffective and better suited to mobile warfare, which was more common in the East. Were technically solid, sometimes even ahead in design but saw limited but useful service, especially outside trench-heavy areas and didn’t influence the war as much as tanks did for the Allies.
