Muzzies get snotted as 60mm mortar misfires catastrophically :)
This is what happens when you use outdated crap ordnance and don't have a clue. Modern mortar rounds have enhanced insensitive performance improving resistance to 'unplanned stimuli' such as this.
If you watch closely there is a flash from the mortar tube followed by the HE charge detonation indicating the propulsion charge either misfired or the round got jammed in the tube. Either way no virgins for these morons...... Awesome...........
