A Quote From A World War II Veteran:

Suppose you are separated from your unit and wander to safety.

You spot a troop in the distance but do not know where they are from. Fire a stray bullet in their direction and see how they react.

If they respond with precise rifle fire, they are British.

If they use a frenzy of machine gun fire, they are German.

If they throw their weapons on the ground and surrender, they are German.

If they try running away, they are Italian.

If they notice you are alone and ask you if you would like to join them, they are Canadian.

If nothing happens at first but about five minutes later the area you shot the bullet is bombarded with heavy artillery, they are American.
