You will NOT get experience for:
Damaging an ally's tank, even if said ally is "blue"
Team killing. But you can always get a free ticket to ban land if you do it on purpose.
Shots that deal no hull damage, destroy no module or kill no crew member.
Shots that destroy a module that had already been destroyed before (except when a repair pack has been used on it).
For receiving damage without fighting back. As stated above, your shells have to damage your attacker.
For receiving titles in the "hero of the battle" window.
For receiving medals or completing achievements.
No bonus experience for a draw or a lost battle.
A specific bonus for "killing all enemy tanks" does not exist, but as listed above, the entire team receives more XP the more damage to enemy tanks is inflicted by the team.
