US Marine Corps - A couple of cogs short of a gearbox.
These are the Scout Snipers. They apparently genuinely did not know that Germanic SS Runes - the white on black is a particularly effective touch - have a different meaning to people who have enjoyed even minimal levels of education.
Expect to see this pic heavily used by Russian/Iranian/Whatever anti-American propaganda.
Edit:
"The SS
sig runes design was created in
1931 when Walter Heck, a
Sturmführer in the SS, drew two reversed and inverted
sig runes side by side and noticed the similarity to the initials of the SS. Heck sold the rights of the
sig runes to the SS for 2.5
Reichsmarks, and the runes were quickly adopted as the insignia of the
Schutzstaffel and became one of the most commonly used forms of
SS unit insignia.

The
sig rune predates the SS but was written vertically and apparently was a sky symbol (like the swastika). It was used in Himmler's Nazi mysticism (see Wiligut Runes) and was based on the "Armenean Runes" of 1902. It is not ancient like the swastika (despite claims of links to the Norse alphabet) but an invented German pagan symbol inextricably mixed up with Naziism and its progenitors.
