Can a commander be a heavy gunner?
Conventional and long followed advice states they can not, but a commander can be a heavy gunner, and it can even be advantageous to do so. Many people who write against commanders wielding heavy guns are thinking about the loss of mobility and the fact that commanders need to be doing a lot of duties in real time. But often the best place that commanders can possibly be is at the front lines. There, you can direct maneuvers as events unfold and react to enemy movements more effectively. Two roles are not even enough. As an example, I am a co-commander of my team and am responsible for almost every position you could think of: scouting, heavy gunning, skirmishing, etc. I often use them all during a long war. Positions in general should be relative to user weaponry class and skill, not rigid assignments. Also positions should change based on the situation. Attacks are also often more successful if led by an experienced commander with a powerful weapon.
