Intended only as a training tank to introduce the concept of armored warfare to the German Army, the Panzer I saw combat in Spain during the Spanish Civil War, in Poland, France, the Soviet Union and North Africa during the Second World War, and in China during the Second Sino-Japanese War. Experiences with the Panzer I during the Spanish Civil War helped shape the German armored corps' invasion of Poland in 1939 and France in 1940. By 1941, the Panzer I chassis design was used as the basis of tank destroyers and assault guns. It continued to serve in the Spanish Armed Forces until 1954. The Panzer I's performance in combat was limited by its thin armor and light armament of two machine guns. As a design intended for training, the Panzer I was not as capable as other light tanks of the era, such as the Soviet T-26. Although weak in combat, it formed a large part of Germany's tank forces and was used in all major campaigns between September 1939 and December 1941. The small, vulnerable light tank would be surpassed in importance by better-known German tanks, such as the Panzer IV, Panther, and Tiger; nevertheless, the Panzer I's contribution to the early victories of Nazi Germany during the Second World War was significant. Later in that war the turrets of the then obsolete PzKpfw Is and PzKpfw IIs were repurposed as gun turrets on specially built defensive bunkers. DESIGN The Panzer I's design history can be traced to 1932's Landwirtschaftlicher Schlepper La S(Agricultural Tractor) armored fighting vehicle. The La S was intended not just to train Germany's panzer troops, but to prepare Germany's industry for the mass production of tanks in the near future. In July 1932, Krupp revealed a prototype of the Landswerk Krupp A, with a sloped front glacis plate and large central casemate, a design heavily influenced by the British Carden Loyd tankette. The tank was armed with two obsolescent 7.92-millimeter MG-13 Dreyse machine guns. Machine guns were known to be largely useless against even the lightest tank armor of the time, restricting the Panzer I to a training and anti-infantry role by design. Page 1 HISTORY The Ausf. A was under-armored, with steel plate of only 13 millimeters at its thickest. The tank had several design flaws, including suspension problems, which made the vehicle pitch at high velocities, and engine overheating. Many of the problems in the Ausf. A were corrected with the introduction of the Ausf. B. The engine was replaced by the water-cooled, six-cylinder Maybach NL 38 TR, developing 98 horsepower, and the gearbox was changed to a more reliable model. The larger engine required the extension of the vehicle's chassis by 40 cm (16 in), and this allowed the improvement of the tank's suspension, adding another bogie wheel and raising the tensioner. The tank's weight increased by 0.4 tons. ENGINE AND TRANSMISSION One of the main differences between the major modifications Pz.Kpfw.I was the powerplant. Pz.Kpfw.I Ausf.A was equipped with the horizontally opposed 4-cylinder carbureted and air-cooled engine “Krupp” M305. Pz.Kpfw.I Ausf.B was equipped with the inline 6-cylinder carbureted liquid-cooled engine “Maybach” NL 38. The transmission consisted of: Reducer, placed directly on the engine Shaft, passing through the crew compartment Twin disk clutch 5 speed gearbox “Aphon-Getriebe FG35” with synchronizer Transfer box for clutch steering and belt/band brakes MODIFICATIONS In 1938 in Spain attempts have been made in order to improve the Panzer I capabilities. There is just one picture in where it is possible to see a Pz. I ausf. A mounting a 20mm BredaModel 35, a short-range anti-aircraft gun. “Thanks Wikipedia” Page 2 GARRY’S MOD REPLICA Garry’s mod Replica I developed this tank to feature similar performance to the real vehicle, based on the data found online. Irregularities on the replicas emerge naturally from this kind of work, especially on such rare vehicles, I did not found any precise values and pictures of such vehicles. MOVEMENT This tank is powered with ACF motors. In is highlighted the 1.4l B4 engine, which provides a very similar power output as the real Krupp engine. This version of the tank has been produced not for much, since the newer Meteor 6 cylinder engine provided much more power and less noise. Note the double muffler on each side of the tank, the meteor variant had a single muffler at the rear. In blue is highlighted the main gearbox: in this case the new stock-ACF automatic 5-speed. This will provide the necessary gear ratios to accelerate, climb and reach higher velocities. Yes, using this tank you are not needed to shift a very stiff lever nor even press a very soft button: it’s automatic. The gearbox presents a very short tranny in order to help the tank get turning from a full stop: this is needed because the engine is very weak. Thin tracks has been simulated with the less draggy rubber physical propriety on wheels. In green there is the dual clutch transfer assembly which enables the steering of the vehicle via clutch-and- brake. As can be noted the tracks are driven by the front sprocket, losing it will result in the inability to throttle, steer and brake. Fuel is not held on this tank since I wanted to reserve the “weakness” of the engine. Page 3 GARRY’S MOD REPLICA LAYOUT The layout follows generally the real tank’s, except for the single command position and the driver seat that is not flat on the floor (and neither is a seat, damned ACF): this is because many ACF servers do not accept standard Garry’s Mod seats as valid for tanks, requiring you to use the much larger ACF Pilot seat or Pod. The image here is presenting the hull’s top view. The ammunition storage is not very big and houses only machinegun AP rounds. It has been proven than the detonation of those munitions many times leaves the tank operational. ARMOR The panzer I’s armor was changed a lot during it’s development, from a maximum of 13mm to much higher values. The reported weight of the tank has been lowered, since this mounts the smaller Krupp engine and thus is a little shorter, missing the rear sprocket. The tank spots a very strong frontal armor, which has been boosted way over 13mm, else it would have been unplayable. Beware the lower glacis, which is still very weak. The side armor is honestly not of much use, since in Garry’s Mod tank encounters are usually at a few meters, the 20mm Breda machine gun mounted on this turret will easily do much damage and tear the tank apart from its sides. The rear armor is even less armored, spotting 10mm effective. Page 4 USAGE Usage DRIVING Control of the vehicle is given by the Wiremod’s Pod Controller : The W key will throttle the engines, making the vehicle move forward, upon releasing W a small breaking force will be noticed. The S key will apply stopping brakes, if both W and S are pressed the engine will spool up with the clutch engaged: this is useful when a greater take off power is needed. The R key will engage the reverse gear and throttle the engines, making the vehicle move backward. The A and D keys will clutch and brake respectively the left and right track transmission. As the real tank’s transmission gearbox this does not allow on place pivoting. GUNNING Upon entering the vehicle, the visual camera will be activated and placed over the turret’s periscope. Moving the mouse will rotate the visual and the turret will slowly rotate to match your target angles. The target can be acquired via the stock game crosshair, which is enabled on this vehicle, except when entering it while holding the camera. By using the MOUSE WHEEL or NEXT/PREVIOUS WEAPON key field of view (zoom) can be adjusted. The machine gun setup is not ideal for armored fights, but can provide a decent tool against transports, infantry and aircrafts. Multiple ammoboxes are used in order to fire 1 tracer every 3 rounds. This simple setup takes advantage of the client-side camera rotation to increase situation awareness, at the cost of fire precision. There is no firing computer as to be expected by such an old vehicle. Page 5 NOTES Notes I decided to share my creations because being able to make good things that not everyone can achieve, just for personal “use” is pointless. I do have like 2000 hours in Garry’s Mod (1500 tracked on steam) and I rarely took my creations to events and servers.
