...What would happen on an all out war between the major powers of our planet? Would we destroy ourselves? Now imagine: What would happen if we were attacked by aliens...in the middle of the third world war...? ...Would we unite and stand as one, or would we divide and fall...? -WELCOME TO Earth Conflict-
The Twin barrel grenade launcher is a upgrade that can be research at the propaganda center
Wouldn't the grenade launcher be a little op ,even if it requires the propaganda center?
It has less range than any anti-armor weapon(105mm\120mm\125mm\155mm\Man-portable-AT Missiles...), can't kill armored vehicles at close range(isn't fast-enough), it will mostly serve to protect it from light vehicles and infantry at close range.
Also, it can't be controlled directly.
So...specialized close-range anti-infantry weapons on a long-range anti-tank vehicle? :S
If you disagree, go argue it with the PLA
En.wikipedia.org
These weapons are found on all modern armoured vehicles.
