Unlock Mercenary IV (more about mercenaries) as soon as possible because they offer you the best rewards and you will need those rewards to improve your stats faster. (higher drop rate for car armament raffle). Work on Advanced Arms – it improves your attack stats, faster troops training, and increases your overkill stat (how many wounded troops are changed to killed when attacking).
If you have a renegade (you should have it, if it’s unlocked), work on Renegades too.
Renegades’ technique and strength improve how much damage renegades can deal. Physique and Protection improve renegades defense.
A very important investment is also crew upkeep reduction (in the Criminal Enterprise category). More about that in Troops’ upkeep.
