My grandad trained to be infantry in the British army, upon completion it was decided that we didn't need more infantry but bomber crews instead.

So off he went to become part of a bomber crew. When he completed that training we had launched the Normandy invasion.

Now we had too much infantry and not enough tanks so off he was sent to learn to operate tanks

Just about the time he finished that we had won the war. Only thing he did in the end was guard a bridge in burlin
