Additionally, Mk is not pronounced as, "Emm-Kay." Mk is an abbreviation of the word Mark (a substitute for model).

If you were asking someone to bring you a Mk 19 (a 40mm, belt-fed, automatic grenade launcher used by the U.S. military), you wouldn't say, "Bring me that 'Emm-Kay' 19," you would say, "Bring me that Mark 19." Likewise, the depth module variants of the Cyclops are Mark 1, Mark 2, and Mark 3 (abbreviated as Mk 1, Mk 2, and Mk 3).
