my only concern with this idea is "require", the way its done with .50 now would be better imo- will make everybody happy
another note is additional work on making assets, but thats another topic
Also, it would hopefully define the roles of a tank crew better. The commander would be in charge, and the other two would be under his command. Right now, there is often confusion when strangers team up to crew a tank, some people think the driver should be giving the orders, others think the gunner.
"hopefully"
with that you have even more possibilities to arguements
I have a better solution. Combine the commander and driver position just as you've combined the gunner and loader position. That way, the tank is used to its full potential and everyone gets something fun to do.
its already combined since like 0.8(or even in earlier versions), the view from top of tank is closer to commander view from it, rather than driver, anyway since 0.9 there are 2 views for it, so it only lacks a .50 access
