The lamda, an inverted ‘V’ is the ancient Greek letter representing ‘L’. it is quite often seen sported on pieces of artwork representing Spartan warrriors, as ‘Lacedaemon’ was the ancient Greek name for Sparta.
I noticed that during Operation Desert Storm and its accompanying operations, that the coalition forces used the lamda as a Tac-sign. Curious, as the war was against what would have been a part of ancient Persia, just as the Greeks fought the Persians (not certain, now, if the Tac-sign was used in the second Gulf War?). Was wondering if anyone had any insight as to this choice of Tac-sign by allied forces and/or is it merely coincidense?
