5-01-11 is the date we finally hunted down ol' Osama Bin Laden (USA date) and this patch is a reminder to those that may harm us. Symbolism wise there are the Twin Towers, the Pentagon, and PA Keystone in the middle to represent the Flight 93 crash site. Geronimo was the code name for Bin Laden.
"After a 40-minute search of the compound, punctuated by firefights, bin Laden was dead, and the cryptic "Geronimo-E KIA" code sent relief through the White House. E stood for enemy and KIA for killed in action." -ABC News
