There are some great squad based fps games out there.
However the game play differs by enemy dispositions and deployment, how well my squad mates interact with me or tensions of close combat.
I have created a method of giving orders which should give the feal of the real life counterpart doing the same,ie how he might have to do it. Orders can be given as quickly as he might have to.
Secondly, I have devised a way of leading by example where your men respond to your example. Although your men can do the job you will not be able to skulk in the background.
Your men will not just blunder into bullets, get shot up several times, survive do it again etc. Yet you cannot just let your men keep getting killed...
So on. I have also eliminated the "Getting continually shot and surviving a million holes in your head" stamina method of the current genre. Neither will it eliminate the playabilty of the game etc. In fact my method may add to the tension of the game.
