When/if we get to the point where it takes a considerable amount of time to enter exit vehicles, I was thinking that perhaps the tank commander should be able to open the hatch and use either his SMG or pistol to dispatch of nearby enemy infantry, although at hightened risk to himself. This would hopefully do away with people teleporting out of their tanks to gun down the enemy infantry who are nearby, something which I consider totally unrealistic and quite frankly, irritating to the infantry.
