The National Lancers use the original 110th Cavalry coat of arms created in 1930.

On it is a Canadian Scottish Rite 30th Degree reference. In the ceremony there are
three skulls placed and the middle one has a wreath around it that represents
DeMolay.

So it is a Knights Templar reference. The Nothern Jurisdiction in Lexington got rid of
that ritual although the Southern in Washington D.C. still uses it.
