True, but also in a lot of cases people use the term "Army" to refer colloquially to all branches of the military.

When I was serving, in 1986, I had a blue uniform and that meant obviously Air Force, but the khaki uniforms were the same for infantry, artillery, tanks, mechanized, radio ops, chemicals, engineers, paramedics etc. Mountain troops had green berets and white anti-vipers socks, and the navy was dressed in white for parades / navy blue for duty. You could see the differences between "greeny" branches only by looking at the small brass symbols on the shoulders and, generally, by the color of the collar patches (red was infantry, but black meant, for example, a lotta branches).

Wrong!!!!! Officer Branch Specialties of the US Army Infantry, Air Defense Artillery, Armor, Aviation, Corps of Engineers, Field Artillery, Special Forces, Chemical Corps, Signal Corps, Military Intelligence Corps, Military Police Corps, Adjutant General’s Corps, Financial Corps. Ordnance Corps, Quartermaster Corps, Transportation Corps, Judge Advocate Generals Corps, Chaplain Corps. Medical Corps. Medical Service Corps. Dental Corps, Veterinary Corps, Army Medical Specialist Corps. Army Nurse Corps.

I am ex army, there is more branches you confusing branches of military with Army sigh. I was in Aviation for instance I enlisted to work on helicopters, there is Administration, Infantry, Field Artillery, Finance, Corps of Engineers, etc etc

marines also go other places when needed. my dad’s a marine and went to afghanistan for a few years.

Its called space force and is a fairytale that evolved in the head of the former precident.

*Space Force

We know you are Nooberton

Well I just don't know how foreign armies work. But in my first language we say "army of air", "army of sea", "army of land". So having an "army uniform" gives 0 information about which army.

No, in the US people use military or armed forces to refer to the military in general.

You realize its a big place and 90% of us do not use Army colloqually. You area yes its weird and not normal, every where I been and I been through a ton of stats not all 50 though people know Air Force and Army are not the same, in fact even small ass towns I been to you say "Aren't Marines same as Army" to an ex marine you might end up with a broken nose.

90% of us know this you got be rich to not know this in US, in fact the least educated people in US know this more as they are the most recruited you got be in super comftable upper middle class or upper class to confuse them in US lol. Like every one I know this they got recruiters since before I was born reminding us in high school of this s**t for crying out loud. Many people do not read the army tag on a uniform though, half time its blocked or they don't see it, and people are just smart asses, its like did its in black not neon pink and they were standing next to you not in front of you. Get the f**k over it. And I am ex Army and saying this s**t mind you
