Both the driver and the gunner may carry a sidearm. I assume that the driver sits on the left side of the car and that the gunner sits on the right side.

Can the driver shoot his sidearm out both the left hand AND the right hand window and can the gunner shoot his sidearm out both the right hand AND the left hand window?

It seems to me that it would be difficult for a crewmember to shoot out of the window on the opposite side of the car with another crewmember partially blocking the window! If the driver tries to shoot out of the gunner's window, it's quite possible he might shoot the gunner!!!
