Oh sure, using a mirror to aim, thats like cheating![]()
I saw this done in a spoof demonstration by the British Army back in the 1960s, A travelling recruitment fair had set up in my local park and was putting on demos twice per day - great fun, Ferrets, Saracens and Saladins chasing each other around firing thousands of 30-06 blanks from their Browning MGs and wrecking the carefully tended turf. Two things really impressed me though. First was the two-inch mortar demo in which inert bombs were fired at a sergeant holding an aiming post. If the aim looked too accurate as the bomb curved down towards him, he'd take a couple of steps to one side! (Not a lot of health & safety around back then.) I watched a couple of squaddies recover the bombs afterwards with spades - they'd penetrated the turf by 18 inches, two feet or so - you'd not want one to hit you on the head.
The other demo was pistol shooting by Sergeant so and so, the 'British Army pistol shooting champion' (the PA said) with the 38 cal Enfield revolver. The 'targets' were balloons tacked onto a rectangular column carried out and set upright by two squaddies. ("Bullet proof - no risk to spectators!" said the PA) The sergeant then proceeded to take ever trickier shots, each successful as seen by a bursting balloon, and the big crowd clapped and cheered ever more enthusiastically. The final 6th shot was (roll of drums on the PA) going to be worthy of Annie Oakley as it's to be taken backwards over the shoulder with a mirror. The sergeant gets into a crouch, squirms around, sights, repositions himself a bit more - really lays it on, the crowd stands silent holding its collective breath - AND ...... the balloon bursts without a shot being fired! The 'pistol champion' lets out a roar of fake rage whereupon the 'target holder' sprouts a pair of green trouser legs and ammunition boots and runs off! Well, there was complete silence from the crowd for about two minutes as it sank in they'd been taken for a ride, then somebody laughed and everybody joined in. The two soldiers came back for a bow and got huge applause.
