What is the history and meaning behind the work "MARK" to designate military
equipment ? The web site www.designation-systems.net says the Navy uses
the Mark - Mod nomenclature but doesn't say what the significance or meaning
of the word "Mark" is. Does anybody know ?

Interesting question. I think it's a borrowing from French. I'd like
to hear an authoritative explanation too.
