delta sierra

This is a military acronym, from the Vietnam war era. It stands for "DS" which is how military personnel would describe a bad situation, or poorly planned mission. It stands for "dog shit."
This phrase is derived using the phonetic alphabet (Military Alphabet). Instead of saying Dog Shit, you would say, Delta Sierra instead so everyone over the radio can understand and know what you mean.
By using the first letter of each word and converting that to the Military Alphabet you get the phrase "delta sierra."
D = Delta
S = Sierra

This mission is totally "delta sierra."

Delta Force

The 1st Special Forces Operational Detachment-Delta is The United States Army's premeir Counter-Terrorist unit. Delta along with Navy SEAL Team 6 (DEVGRU) and The Air Force's 24th STS form JSOC (Joint Special Operations Command.). Delta Force usually recruits primarily from the 75th Ranger Regiment, yet many Delta Operatives have earned their Green Beret and went through Ranger School before going through Delta screening. Delta Force has been rumored to have a drop out rate of 99.972%. (Example: If you gathered 100,000 fully grown, adult males only 28 could pass Delta screening.) Delta also cross-trains with The British Special Air Service and other Special Forces units of Allied countries.

Earn a Green Beret, get your Ranger tab, go through Delta Force Screening and maybe cross-train with The Grandfathers of Special Operations (The British Special Air Service.). How many people could do it?
