The Inverted "V" - Used for vehicle night combat identification. Designed for night viewing with NVG/NOD's. Black IR reflective inverted "V" symbol. Reflects only IR light. The inverted V symbol represents a Spartan saying, Molon Labe! (mo-lone lah-veh) or "Come and take them!", "Come get them!", or "Come get it!". The closest translation would be the first "Come and Take Them!". Here is a very brief break down of the story behind the "inverted V": The story is that the Persian King sent a messenger telling the Spartans to lay down their spears and they would be spared. The Spartans cut off his head and inscribed "Molon Labe" (Come take them) and sent it back to the Persians. There were only 300 Spartans, they held off 1,000,000, what more can be said. I hope this helped.
