Once a heavy weapon has been exhausted how does one use it again? Must you just have to wait a full turn for it to recharge? Also when one buys the impact gear upgrade does every trooper get it? Thanks for any help that you can give.

1. You must use a recover action

2. Every trooper can use the grenade and impact on the grenade stacks.

Recover - A unit can recover by performing a recover action. When a unit recovers, a player removes all suppression tokens from that unit and readies all of the unit’s exhausted upgrade cards.
