Back to apocryphal tales:
The true bit: A Chinook, on ops, lands to emplane the troops. Ramp goes down, platoon (of Paras) run aboard. One individual trips and, as he falls forward, looses off a burst into the Chinook floor (luckily, not much under the floor).
The apocryphal bit: The soldier was said to be berated by his RSM for poor grouping!
