Reinforcement

[Novaliz]

Im new in Men of War and I have some multiplayer questions.

1)How does the reinforcement works. for example it says +15 to get a Tiger. How do I get this +15 points? Time or kills?

2)How many units do u buy at the beginning of a game. Do u always have ur full manpower used?

3)Is there a good community side (all language) which explains something about the units and so on...?

thx ahead!
