A deck of cards (usually an ordinary set of 52 or 54 playing cards) on which is printed the names and photos of individuals considered by the card printer to be important persons to commit to memory, to make it easier to find and capture them (or kill them).

The official military term for this is "personality identification playing cards".

For the Second Gulf War, Coalition troops were given personality identification playing cards with the names and pictures of Iraq's most wanted.
I could tell the most-wanted deck I got on E-bay wasn't authentic, because while Saddam Hussein was the Ace of Spades, Tariq Aziz was the Eight of Clubs.
