as a response to DJ Furby, who commented a bit ago, csualties are getting hit, not just dieing. if 8 soldiers die, I don't think they'll all be killed with one shot. so, you probably had about 13-14 casualties.
There's a sorta glitch where if you have propper planning and The ribbon giving 1+ tac pints at start, you go to close protection or whatever one starts you with 12 in ur case 13 points, quit, then keep going to proper planning and quiting repeating you get 20 tac points
the reason you can get the ribbon for airstrikes is because the 20mm cannons fire identical shells. i don't knoe if it's a glitch, but you can aquire the airstrike badge with the 20mm cannon
