My personal favorite:
Errr... - (U.S. Marines) An abbreviated or unmotivated "Oorah". Often used as a form of acknowledgment or greeting. Yes, we really do walk around saying "Errr" at one another in the way normal civilized humans say "Hello."
And other notable euphemisms.
5 fingers of death - (US Army, US Marines) Another name for the MRE beef franks, so named for their number and unpleasant taste. Also known as "Beans and motherf******" for the same reason. Later versions of this meal only contained four beef franks without any beans or sauce and were subsequently nicknamed the "4 d**** of death".
BGB - (US Navy and Marines) Big Gray Boat. Refers to large ships, e.g. carriers and battleships, that are gray in color.
Bird, Ball and Chain - (US Marines) Cynical term for the Marine Corps' Eagle, Globe and Anchor emblem.
boot - Someone lacking in experience. A reference to "boot camp".

Bullshit flag, throwing the - (US) Challenging the factual accuracy of another's statement.

chem light batteries - (US Marines) A form of snipe hunt. To have a new Marine search for obviously non-existent batteries for chemical light sticks.
dark green - (US Marines) An African-American US Marine; as compared to a "light-green". Intended to promote a sense of oneness among Marines "All Marines are green." Becoming an archaic term; sometimes perceived as offensive instead.
Devil Dog - (US) US Marine. The term comes from a (possibly apocryphal) complimentary term,Teufelhund, applied by German soldiers to Marines during World War I for fighting like shock troops.
firewatch ribbon - The National Defense Service Medal, which is given to all members of the military during a wartime event. It is presented during bootcamp and everyone gets one, so among the military people serving beside you... no one cares. Firewatch is a reference to the guard duty you do while at bootcamp.
Good Cookie - The Good Conduct Medal, which is presented to naval and Marine Corps personal for every three years of service without a major disciplinary offense.
Grape - 1. (US Submarine Service) Delightfully easy. Examples: "This is %$# grape duty! I %$# love it!" or "That was a grape sig, you %$#." (See "sig" below)
2. (US Marines, Army) One's head. For example: "Put your cover [hat] on your grape."
3. (USAF Fighter Pilots) : an aircraft/pilot that is easy to shoot down.
4. (US Navy) : The flight deck crewmen on an aircraft carrier tasked with fuel handling (so called for their purple shirts and helmets) . Related to "skittles".
