Driving rugged vehicles in a combat situation is second nature to the Soldier. They measure their shots and navigate obstacles with a subtle timing that doesn't affect the steadiness of their own or their passengers' weapons. Firing a few shots through the windshield or window while performing dangerous driving maneuvers is also no problem.
Passive, always in effect. Must be driving a rugged vehicle, such as an SUV, truck, or armored car. If you would split your dice pool between driving and another action, you get a full pool for both actions. The motion of vehicles you are driving never causes your passengers dice penalties, and you do not suffer dice penalties from the unsteadiness of any vehicle you are riding in.
