Smoke Launchers
These carry charges that can be fired to hide the vehicle behind a cloud of smoke. Once per game, after completing movement (no matter how far), a vehicle with smoke launchers can trigger them. Place cotton wool around the vehicle to show it is concealed by smoke. The vehicle cannot fire and use its smoke launchers in the same turn. Any penetrating hits scored by the enemy in their next Shooting phase count as glancing hits. After the enemy's turn, the smoke disperses with no further effect. Note that a vehicle may still use smoke launchers even if its crew are stunned or shaken.
