Anyway, I loved the origanal Sudden Strike, but can't really get the sequel just yet, as I'm still playing through Warcraft 3 and Project IGI. As soon as I'm done with those though, I think it'll be time to sink my teeth into more WW2 stratagy action that SS2 should offer, and maybe Mafoa as well.
Anyway, like Beanz said, to resuply tanks, cannons and troops, just send a supply truck close to the vehicle you want to rearm. The truck should automatically resuply you vehicle with any ammo it's depleted.
They can also be used to repair any damaged tanks and armoured vehicles.
