Yellow Military

What is the name of that sash thing on military uniforms that go under the arm and is usually blue or yellow?

This is better than a simple, Officers wear aguillettes

[edit] United States
The aiguillette, or fourragère, is worn by soldiers and Marines who are assigned to units that were awarded certain decorations by the French Government for valorous conduct in the First and Second World Wars (see fourragère for details). It is also worn on the right shoulder by military aides to the President of the United States. It is worn on the left shoulder by aides to flag officers, military attachés, General Staff Corps officers, and United States Navy boot camp Recruit Division Commanders. Navy Aides wear blue and gold cords, while Recruit Division Commanders wear red. A blue aiguillette is worn on the left shoulder by Cadets in Charge of Quarters at the United States Air Force Academy, as well as by Military Training Leaders at technical training bases. Student Airmen leaders at technical training bases (sometimes called "ropes" in reference to the aguillette) also wear aguillettes, with green representing the lowest level of student leadership, yellow representing the intermediate level of student leadership, and red representing the highest level of student leadership. In the United States Air Force as well as in the Civil Air Patrol, Honor Guard members wear a silver aiguillette on the left shoulder. CAP cadets acting as Cadet Advisory Council Representatives at the national level wear a gold aiguillette, at the regional level a blue aiguillette, and at the wing level a red aiguillette.

A similar device, the blue infantry cord, is worn on the right shoulder by enlisted soldiers and officers serving in infantry and airborne infantry units
