This feature would allow for bigger maps and a player cap increase, both should scale accordingly to maintain a good pace of battle. Aggressive players will do what they do best but also get the option to push further in and slow down reinforcements (raiding enemies back line would be more inpactfull). Players who usually play the back line would help in reinforcing and maintaining ally space secured or increase the speed of reinforcements by using transport vehicles. Attack vehicles would benefit simply from having more space to maneuver, allowing it to hunt units that lack proper counter measures or harras and halting enemies advancement by using guerrilla tactics (shoot and run)
