Agreed with Graham. Most vehicles relied on their organic .50 caliber machineguns for self defense. Trucks, halftracks, and tanks all carried them. The dedicated AA battalions (still considered part of coast artillery then) did have self-propelled halftracks (M-15 type) with a rotating partially open turret mounting 1 x 37mm and x2 .50 caliber watercooled machineguns. Not sure if they shot on the move a lot though, as it makes it doubly harder to hit a plane when the vehicle and aircraft are both moving (well, one is moving and one is bouncing up and down). The AA vehicles probably moved off the road a short ways and halted to fire. I think commanders tended to deploy their AAA near artillery units to ensure their indirect fire capability could not be disrupted by Stukas and Jabos.
