This is a tried and valiant soldier who risked his life in the battlefield while you were safe at home in your  hide. He risked his life for  you. Harper never served one day in the military and hid like a  coward in the cupboard during a terrorist incident. Sajjan would have come out and fought like a lion. 

He, like all old soldiers, sometimes exaggerates about his battles. Big deal ! If he had been white the press would just chuckle and pass on.
