Too often are BMPs and MBTs abandoned for the majority of games on the Insurgent and Militia factions. It is obvious that the firepower and accuracy of their vehicles vastly under-performs that of all other armies, so most players on those armies go for the smarter strategy of simply ignoring those vehicles and spamming their multiple HABs, instead of sacrificing 2 or 3 players to pilot and gun the loud, slow BMPs and MBTs that have far inferior turning speed and optical zoom and clarity. 

If these two armies could one man their vehicles, it would drastically increase the rate at which Insurgents and Militia take advantage of the tools the developers gave them without losing an unnecessary amount of infantry. Often times the real world counterparts to these factions do one man vehicles due to lack of manpower and expertise.

So please EasyCompany, allow the Insurgent and Militia factions to be the true irregular and chaotic factions they were designed by the game devs to be.
