And still the infantry tree is so vulnerable and buggy. If it will not be fixed I will not purchase the game.

* there seems to be a forced auto-selection of transport trucks and squads when you command them to embark, thus when you select another irrelevant unit and command it somewhere both non-embarked selected squads and the previously selected trucks will move there, whereafter usually most of the embarking fails and must be performed again or what's left of it. It decelerates you, especially during overture for example when immediate conquest of points is necessary and no one else is nearby to do so.

* infantry's mobility is poor meaning great vulnerability, though it can be remedied by, indeed, hasty transportation (trucks, armoured cars, transport choppers), but unfortunately they are expensive severely reducing your chance at an effective combat force. Trucks are reasonably cheap -- and even then you will have limited fighting capability -- but they easily perish by enemy choppers (and armour). If you're unlucky to have your troops inside they will die alongside the transport unless you unloaded them in time.

Teamwork in this regard is possible, but will most likely not occur because it requires coordination by proper communication -- something usually lacking in public games.

* if there is no cover, your infantry are even more vulnerable.

* cover such as trees and buildings perish easily.

* if your infantry has been spotted usually the nearest cover to which you flee is the most obvious target for airstrikes. Where else must an infantry player go to be safe? One simply directs napalm or chemical weapons at buildings and forests and they are done. You could choose to not run into forests which is unexpected, but if enemy ground units engage you any kind of relocation is futile and there isn't much left to do than to engage suicidally, going down, and taking as many foes with you as is possible.

* infantry is easily spotted by choppers even if you are in heavy deep cover again such as forests. If you're right in the center of it and they fly over they see you. How should that be possible? And if you have your squads set to 'hold fire' they still fire and are detected. Napalm, large area, boom, done.

* due to the tricky balance between mobility and combat power, you'll hardly ever have superior infantry ably taking on foes.

* prices, again, are too high for what you get in return.

Overall, it requires extreme micromanagement (and luck) for infantry to be effective -- more than other roles. And they are buggy, and they are -- compared to others -- expensive. Infantry should be the best damn role in the game because it's always the foot soldiers who are versatile, effective, and sneaky. When still -- even when moving -- they should be not or hardly detected. Even (bombed out) buildings should provide cover and stealth.

The combination of overemphasis of easy airstrikes, artillery, general raw power (including illogically fast tank runovers of entire squads), infantry's weak anti-air and anti-tank arms, the difficult balance between mobility and power, etc., makes infantry the toughest and most frustrating tree to play... but also the most rewarding and satisfactory if you succeed.

It is either hit or miss.
