Well, maybe I should explain further!
In the mission I'm making, the player is a platoon leader of a mech. inf. platoon with about 40 soldiers, which is a lot to command in Arma. I want to try to give it a platoon leader feel to it without making the player want to commit suicide because of the stress it would involve to command so many soldiers like you do it in Arma. (The way I see it, Arma is normally ideal for squad leader missions.)
I don't just use teamswitch, because I want the player to play the whole mission in character as the platoon leader!
I've made some GameLogic waypoints for the player to command his platoon through, like attack the town, defend the crossroads, fall back, etc. This works fine with me because a platoon leader isn't supposed to command soldiers directly anyway, but through his squadleaders. The reason I want the squad toggle thingy is because I want the player to have the freedom to improvise and do things differently if he wants. I just thought it looked a bit ugly using up two radio commands for each squad instead of 1.
I'll upload the mission when its done so you can get a clearer picture!
I used Loyalguard's suggestion and made a global variable as my toggle which works perfectly!
Thank you all for your ideas!
