Some questins.

I got some questions about this game.

1) What are the bonuses your units get when they gain in rank? I've noticed snipers move faster while they'r camouflaged, and the german tanks get gunners and side skirts. But i don't know it for the rest.
2) When i research production level 1 and 2, the cost of my troops don't change. I've done it several times. What does it do?
3) How does the ranking system in multyplayer works?

1) there is a really nice site for this: http://www.coh-stats.com/
2) reduces upkeep of troops.. so you get more manpower income
3) you gain / lose points for winning / losing ranked matches. (so only the matches you play by clicking "play now")
