3 HISTORY History The T-70 was a light tank used by the Red Army during World War II, replacing both the T-60 scout tank for reconnaissance and the T-50 light infantry tank for infantry support. The T-80 light tank was a more advanced version of the T-70 with a two-man turret: it was only produced in very small numbers when light tank production was abandoned. The T-90 self-propelled anti-aircraft gun was a prototype vehicle with twin machine guns, based on the T-70 chassis. The T-70 was armed with a 45-mm L/46 gun Model 38 with forty-five rounds carried, and a coaxial mm DT machine gun. The tank was operated by a driver and a commander who loaded and fired the gun. Armor thickness on the turret front was 60 mm, turret sides and rear: 35 mm, hull front and sides: 45 mm, roof and bottom: 10 mm. PRODUCTION HISTORY By 1942, light tanks were considered inadequate by the Red Army, unable to keep up with the T-34 medium tank and unable to penetrate the armor of most German tanks, but they could be produced by small factories which were unable to handle the large components of medium and heavy tanks. The T-70 was an attempt to remedy some of the shortcomings of the T-60 scout tank, which had very poor cross-country mobility, thin armor, and an inadequate 20-mm gun. It also replaced the very short production run of the T- 50 light infantry tank, which was more sophisticated, but also much too complicated and expensive to produce. The first batch of T-70s were built with a GAZ-202 automotive engine on each side of the hull, one driving each track. This arrangement was seen to be a serious problem, even before the first tanks were issued. It was quickly redesigned as the T- 70M (although it continued to be referred to as just T-70), with the engines in-line on the right side of the tank and a normal transmission and differential. The conical turret was replaced by one more easily welded out of plate armor, and moved to the left side of the hull. Curiously, even after the T-70's production line was redesigned, SU-76 self-propelled guns started to be built with the same unsatisfactory unsynchronized two-engine layout, and all of them were later recalled for factory rebuilding as SU-76Ms. Page 1

4 HISTORY T-70s were put into production in March 1942 at Zavod No. 37, and along with T-60 production at GAZ and Zavod No. 38. They completely replaced T-60 production in September 1942, although that tank remained in use until the end of the war. Production ended in October 1943, with 8,226 vehicles completed. The T-70 remained in service until DECLINE OF LIGHT TANKS The one-man turret of the Soviet light tanks made coordinating a tank platoon nearly impossible, because the commanders were kept busy acquiring targets, loading and firing the main gun and machine gun, and commanding their drivers. The infantry tank role was already considered obsolete. The SU-76 self-propelled gun was better suited for infantry support, its 76.2-mm gun capable of firing a larger high explosive shell. Industrial resources could be redirected from light tanks to building SU-76s. In November 1943 Red Army tank units were reorganized: light tanks were replaced by the T-34 and the new T variant, which started production the following month. Light tanks continued to be used in self-propelled artillery and some other units. Thanks Wikipedia Page 2

5 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. MOVEMENT This tank is powered with ACF motors. In red 2 I4 1.5l engines provide a very similar power output as the real GAZ-202 I6 engines. 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. In green there is the dual clutch transfer assembly which enables the steering of the vehicle via clutch-andbrake. As can be noted the tracks are driven by the front sprocket, losing it will result in the inability to throttle, steer and brake. A little reserve of fuel is provided for sake of realism, the engines are diesel and behave pretty much like the old agriculture petrol engines; when the fuel is depleted, under stock ACF, the engines will still work with reduced power.

6 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: 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 quite low; occupying only half of the available hull s height, there is space for a secondary chair when converting this tank in a twin-manned vehicle. ARMOR This tank armor follows pretty much the standard values for the T-70M Light tank. The turret has been lightened since there are no sensitive components inside it, thanks to that weight saving it has been possible boost the side armor from 45 to 50mm as well as the front lower glacis. The tank spots a very strong frontal armor and has the ability to bounce many incoming shots (from contemporary guns). The side armor, even if it has a similar thickness as the front, is much weaker since there is no slope helping. The rear armor is even less armored, spotting 37mm effective thanks to the slight slope. It should be kept in mind that this tank can be one-shot easily from a short 75mm cannon (Panzer IV) if shot directly at the side (~40 ), fortunately the T-70 is much more agile. Page 4

7 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. Keep in mind that the short cannon is not very precise over long distances. 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

8 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. Keep an eye on my website for more complete contraptions, E2 code and non-coded modeled chassis.
