Everyone had a situation, when some units after they performed the planned action became useless, especially when another class of units is needed. What do players usually do in this situations? Send them to death to enemy troops or merely press "dellete".
It will be more realistic and useful, if there will be an ability to "demobilize" a squad in headquarters: units will disappear and player will get some ammount of requisition: Full original requisition cost for each healthy unit and less requisition for wounded. What do you think about this?
