There are several modifications made on M-84. It looks like T-72 but it is not the same. M-84 is popular tank, was sold to many countrys in middle east. It was used in desert Storm and showed even some advantages to American M1A1, had less mallfunctions, it is harder to spot it then US tank. I know that it is not much different but, it would be more accurate.
Also, there are some interesting infantry combat vehicles that can be used and are, also, authentic like M1 BOV, M-80, M-90 (rescue tank, for pulling out damaged vehicles fromm battle). Also, few Serbian made anti-tank rockets like Bumbar. Croatian side used Mi-24 helikopters, aircrafts can be intersting to see like G4, Orao, MiG 21, MiG 29...
I am not saying this in the bad way. I realy like the idea and want to play this game. I almost had some expirience in this war, and some my friends, on all sides had they expirience.
Oh yes, sorry for my English but... better then to write this in Serbian:)
