According to Resolution No. 46, passed in spring 1965 by the National Executive Committee,
Please wear your uniform cap when attending Legion meetings and doing the good work of The American Legion.
All officers are expected to wear an official Legion cap and the official badge of office.
The color of a Legionnaires cap reflects their level of leadership responsibilities. For a visual perspective on what color caps are worn by different levels of leadership, take a look at the pictures of the 216-2017 Department officers published in the July/August edition of the California Legionnaire newsletter.
This simple explanation of the term "Blue Capper" is presented by Charles Schmidt,
2016-2017 National Commander, The American Legion.
The Post Officer Guide and Manual of Ceremonies states the following about the uniform cap.
"Wearing the American Legion cap, uniform and regalia
1. The Legion cap, uniform or regalia should be worn by its members only when in attendance at official Legion meetings or ceremonies, as official guests at patriotic or other civil functions, or by individuals when officially representing The American Legion on public occasions. For all ceremonies, the uniforms adopted by a department are recommended. However, an official American Legion cap, dark blue or black civilian coat, dark trousers, white shirt, black four-in-hand tie, black shoes and socks make an attractive uniform. A Legionnaire is considered to be in uniform if wearing an official American Legion cap. Therefore, it is not proper to wear a Legion cap while eating a meal at an official American Legion or civic luncheon or dinner.
2. The cap should be worn in a place of worship only by the guard of honor, color guard and commander of the same while in marching order or standing guard. When one is seated, the cap should be removed.
3. Posts marching in formation into a place of worship should uncover at the door, hold the cap with the right hand over the heart until arriving in the pews and commanded to take seats, and remain uncovered during the entire service. At the close of the service, upon command, the post shall rise, hold the cap with right hand over the hearts, march out of the place of worship, and recover after marching through the door. Note: The cap should be held over the heart as one approaches the casket, and is not at any time worn in a place of worship except by the guard of honor, color guard or commander of same while in marching order or standing guard.
4. Legionnaires not in formation will uncover upon entering the place of worship, remain uncovered during the entire service and re-cover after leaving the place of worship.
5. At the graveside, the cap should be held in the right hand over the heart during the entire service. In cold and inclement weather, the cap should not be doffed.
6. In meetings, the cap should be worn except during the Pledge of Allegiance, prayer and while standing in silent reverence in memory of departed comrades, when it should be held with the right hand over the heart.
7. A Legionnaire wearing a cap should behave in proper accordance as to salutes, etc., the same as if wearing a military uniform. If not wearing a cap, observe ordinary rules of etiquette for civilian dress.
8. Female Legionnaires should wear their caps in the manner prescribed for women in the armed forces. This is suitable for most situations, but taste and common sense should prevail. By American Legion tradition, a female Legionnaire may leave her cap on during the Pledge of Allegiance, the national anthem, prayer and meals.
9. Legionnaires wishing to attach decorations and/or other official insignia to their caps are advised of a National Executive Committee resolution on the subject, excerpted below."
