To hell with reassuring looks... Give it a mask that looks like Angelina Jolie. Now THAT'S REASSURING.... And even if the soldier die. At least the last thing he sees is a HOT girl. Better still makes the robot say something "reassuring" like... "Oh, baby.. plz dun die. I need you"... I bet you the chances of survival of wounded soldier will increase 10 fold.
Well... either tht or u be seing more soldier get "injured" just to ride her. Hahahaha
