I haven't played this yet but I played the OFP CTI version(s) to death and have read all of this thread and the warfare manual so thought I give a suggestion for what I'd like to see added.
1) My first suggestion was going to be give the commander the ability to give missions or allow the player to chooose missions for the player to undertake. I see that's already there so I'd like to see the the missions that can be given expanded for more options.
2)I'd like to see the commander be given the ability to give out roles to players(the player can always choose to reject them). The roles would be the same as the AI are given (light, heavy, air and so on...)
3)If the players can be assigned roles by the commander I'd then like to see some sort of auto-buy button. When one clicks it troops and vehicles would be bought according to some algorithm which would be the best match between the players role and what he can afford. So ,for example, if one took on the air role one would be automatically be bought troops and ground vehicles until one can afford aerial stuff. And for the heavy role, light vehicles until he can afford heavy.
That's all.
