Once a Indian Army camp in Sri Lanka was overrun by LTTE..Most of the troops were killed and one Cook was captured.
Carl Gustav was admired by the LTTE and they captured a few.
So they didnt kill the cook who was from Haryana or Rajasthan and made a deal with him that if he teaches them how to operate Carl Gustav they will leave him.
So he told them who at the time were 3-4 in number to stand behind the RL for better understanding the working.
As soon as he choked the trigger all 3-5 LTTe got hit by the back blast and this guy took a AK from them and ran away in the jungle.
Was awarded also if i am not mistaken.
