In a deck of playing cards, the Ace of Spades is commonly thought of as the highest card in the deck, although the actual value of the card varies from game to game.
The Ace of Spades has been employed, on numerous occasions, in the theatre of war. In the second World War, the American 101st AirborneArmy Division were marked with the symbol painted on their helmets. In this capacity, it was used to represent good luck, due to its fortunate connotations in card playing.
Some twenty years later, the Ace of Spades was again used by American soldiers - this time as something of a weapon in the Vietnam war. Vietnamese ancient traditions held the symbolism of the spade to mean death and ill-fortune. The soldiers were quick to pick this up, and in a bid to scare away Viet Cong soldiers without firefight, it was common practice to litter the forested grounds and fields with the card. This custom was believed to be so effective, that the Bicycle Playing Cards company was asked to supply crates of that single card in bulk. The crates were often marked with 'Bicycle Secret Weapon.'
