Honor Guard

I have recently been appointed and was wondering if anyone knows where I can get more information regarding the Honor Guard team. I am a member of my AFJROTC Honor Guard and might be interested in joining at the Academy. Does anyone know how it works? Can anyone join or are there tryouts? Also besides color guards and drill routines are there any other ceremonies that the Honor Guard team does (like POW/MIA table, for example)?

Thank you
