What do the different color berets in the Army signify?

Black - Low Speed High Drag
Maroon - High Speed Low Drag
Tan - Bad A$$ Michael Foxtrot
Green - Insanely Bad A$$ Michael Foxtrot, facial hair optional

Just to put this in perspective, this comment is just simple Army humor about beret colors and what units wear them. No disrespect to anyone's achievements or merits is intended based on what beret they wear/wore.

I'm was a commo guy and our chief of police flew Cobras. He calls me, "cable boy" and I call him, "rotor head."

All - Thank you for your willingness to explain the beret to an outsider. From the time I saw the movie "The Green Beret" I always had great respect for those men and their uniform. However IMHO they are the only ones I ever thought looked good in a beret. Any other time I see one I tend to think it and what it takes to earn one has been... well borrowed. Again in my opinion if you have a Ranger badge that already says you are a bad ass, if you have jump wings it already says there is something very seriously wrong with because you will jump out of a perfectly good aircraft. lol - Yeah you guys don't need a hat that is also worn by girl scouts and snooty French artists. You all have my respect.

What bothers me now after learning all of this is I now know that Bergdhal is Airborne. He is obviously the odd man out when it comes to that very honorable group of men.

Black: Let's see if we can simultaniously piss off the Rangers AND everybody who isn't a Ranger.

Before the changeover in 2001, the green beret signified Special Forces, the maroon signified Airborne, and the black signified Ranger. The black beret was "taken" from the Rangers and given to the whole Army as the new headgear. The Ranger black beret was changed with a tan beret.

That someone at or above the O-7 pay grade has nothing better to do, or, is looking for their next star.

Cpl Fermil, here is a good link to find out the history of the military use of the beret.

I particularly like this line: In 1951, the Marine Corps experimented with green and blue berets, but dismissed them because they looked too “foreign” and “feminine.”

In general, the only use the beret has these days is to distinguish "special" units and provide esprit de corps. Practically, the beret is horrible. It holds in the summer heat, provides no shade from the sun, stinks when wet, and once it gets dirty it is ruined. The patrol cap is much more practical as a daily duty uniform headgear. The beret does, however, look really good with dress uniform and jump boots. I happened to be in Korea when the black beret was mandated for wear by the Army. It was horrible. There is an elaborate ritual to prepare a beret for wear that includes shaving and shaping the beret. There is also a particular way that the beret should be worn. I was one of the only airborne troops in my unit in Korea, so it fell to me and one or two others to educate the entire unit on how to prepare and wear the black beret. Oh, the horror! Those guuys had no clue how silly they actually looked.

my personal favorite beret comment was from Marine Commandant Krulak. When asked about a uniform upgrade to a beret, his reply: “I don’t want my Marines looking like Frenchmen”

Green (Special Forces)
Red (Airborne)
Tan (Ranger)
Black (Feel good beret)

The special forces Green Beret color is homage to their connection to the British Commandos during WW11 who wore that color. Do knot know what the green specifically means though.

Ranger Regiment Tan Berets: Black used to be the color they wore until the (poor) decision was made to make black the army wide color. Tan was used to replace the (stolen) black. The tan color symbolizes the buckskin caps worn by the Rogers' Rangers during the French and Indian War in the 1750s

Airborne Maroon Berets: First worn by British airborne under General Frederick Browning. Supposedly the color was chosen by the General's wife. I don't think it has significance other then what it has now earned as an international symbol of airborne forces.

If anyone else knows more specifics about the meanings of the colors, please chime in.
