Smoke Grenade. The guard throws a smoke grenade up to 60 ft. One round after it lands, the grenade emits a cloud of smoke that creates a heavily obscured area in a 20 ft. radius. A moderate wind (10-20 mph) disperses the cloud in four rounds, a strong wind (>20 mph) disperses it in one round. The guard can use this ability twice before having to restock.
