Illegal loadouts

[Muleo]

Reverse engineering, mass production of weapons and spare parts. Realistically, virtually every major faction would have access to almost every weapon in the game, through espionage, salvage, etc, save for such instances where there is almost zero contact with another faction, Liberty and the Corsairs, Mollys and the GMG, for examples. Enemy factions within close proximity and in constant conflict would almost certainly have acquired enemy technology and put it to use, if found to be worth using. Pride only makes you obsolete and dead in such a situation.

And why is it countries like Iran are buying weapons from other countries instead of producing it themselves?
