Okay, a few terms need to be defined.
When we are discussing the JROTC rule, we are discussing the hijab. Now, here is the problem: AR 670-1 allows religious garments only if they do not conflict with the proper wear of the uniform. A Yarmulke complies with this, as does the skull cap that male Muslims tend to wear. A Turban is a bit more problematical, but the way that other armies have gotten around this is to establish Sikh regiments whose duty uniform includes the turban. Given that the US military already has separate headgear for different units (Airborne, Ranger and SF), it is conceivable that a Sikh exception could be made, but only if they formed separate units, which would defeat the purpose of integration into the armed forces. Separate uniforms for ethnically segregated units would be a horrible precedent to set, as would permitting the wear of items which are not uniform in order to promote ethnic or religious separatism.
- The Hijab is the head covering, usually a scarf that wraps around the head and hides the hair.
- The Chador is the full-length cloak that covers a woman from the top of her head to her ankles, and has a hole which allows her face to be seen.
- The Niqab is the the face veil which, when worn with the chador, completely covers every part of a woman except her eyes, hands and feet.
- The Burqa is a full body garment that has a screen in front of the eyes and only permits the hands and feet to be seen.
