Hello All,

Today I would like to suggest the addition of the V-150 Commando(Diesel) with the 20mm Oerlikon 204GK Autocannon Turret.

In one of my other suggestions for the V-150 base chassis + Drive-train combinations, someone asked what the rate of fire of the 204GK was, so, you’ll be able to find it here! Note, that the armor angles for the turret are not set in stone, they were estimated using Photoshops line tool and multiple diagrams. This also happens to be one of the versions that I do have solid vehicle weight and other information on.

The history of this variant is pretty straightforward. The 20mm Oerlikon 204GK Autocannon turret was offered as an option with the original Hull/Drive-train combination from 1971, this particular version is a 2-man turret. This version of the vehicle uses the standard V-150 chassis with the Cummins V8-210 8.3L (504ci) Diesel Drive-Train, which was introduced around 1979. This version having the 2 man turret brings the crew total to 4 - Commander, Driver, Gunner, Radio Operator.

It’s unclear as to how many countries have had this variant in service, all the export information I can find so far only lists V-150s as V-150 APC or V-150/90, or ARV. From the pictures I’ve seen, it’s been used by and in Haiti, it was tested by the US Marine Corps and was available as a turret option for the V-150/M706 Product Improved vehicles operated by other branches of the US military.

This Vehicles Place in the Game

To be honest, this one is a bit tricky. Its armament isn’t overly powerful, and the turret isn’t stabilized. However, it does have a very high rate of fire for the main weapon and decent armor penetration with the AP round. It’s relatively speedy for an armored car, and would even have good off-road performance. It would have similar off-road performance and firepower to the R3-T20, though it would be slightly slower on hard roads, but, it would be more stable in turns, as it’s able to easily handle side slopes of 30% (16.7°). It also has a higher turret traverse and elevation speed than the R3-T20.

However, I also would not like to see a repeat of the issues with the R3-T20 where it would be facing World War 2 vehicles. This would have limited use against most rank 4 or early rank 5 medium/heavy tanks. But, it would tear up most lighter armored vehicles. Especially as you get towards the lower end of Rank 6.
