get the gun, then turret and then hull

the hull is a unique missile launcher platform that cannot change any parts and it gives you a taste of a different playstyle on some of the larger maps but most of the time you should continue with the mirage hull.

the turret is a very popular light tank turret as it gets a high reload multiplier and a co-ax 30mm autocannon as well as being fairly short.

the gun is a direct upgrade to the 100mm Molotok
