Its 280mp and you would get free weapon racks and nades (300mp). Since you dont need to factor in officer squad, you can open with 4 rifles without murdering upkeep. Thats a buff.
4x rifles + 200mp tech + 50mp tech = 1370 manpower for 4 squads and light vehicle tech and both side techs, one of which (grenades) you usually do not need.
Or 4x rifles + 200mp tech + 200mp tech = 1520 manpower for 4 squads and both support weapons techs and side techs.
versus
3x rifles + free officer + 200mp tech + 50mp tech = 1090 manpower for 4 squads and tech and you can choose to only unlock Weapon Racks (1090 + 150 = 1240 manpower).
2x rifles + free officer + 200mp tech + free officer + 200mp tech = 960 manpower for 4 squads and support weapons tech, 50mp more if you want light vehicles (which you don't necessarily need in team games), and you can choose to only unlock Weapon Racks (960 + 150 = 1110 manpower).
Now I don't know about you, but I'd rather take the latter two and fight without grenades, and use the manpower I save to get an M2HB or something.
