Smoke Launchers

Some vehicles have small launchers mounted onto them that carry smoke charges (or a more sophisticated equivalent in the case of skimmers). These are used to temporarily hide the vehicle behind concealing clouds of smoke especially if the vehicle is moving out in the open. Once per game, after completing its move, a vehicle with smoke launchers can trigger them (it doesn't matter how far it moved). Place some cotton wool around the vehicle to show it is concealed. The vehicle may not fire in the same turn as it used its smoke launchers, but 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.
