military haircut

When you join the military, you expect certain things.  You become governed by rules and regulations.  If you don't like them, get out.  A transgender person named Chelsea Manning is upset that she has to have a 2 inch hair cut.  Doesn't everybody in the military have short hair?  Or am I mistaken?  My daughter is allowed to have a little bit longer hair now that she's been in for 16 years but it always has to be up and most of it has to be under her cover.  I'm guessing if other women in Chelsea's unit have longer hair, then she has a case but if not, it's time to get out and find a different career.  short hair
