Three types of MCJROTC uniforms that you be involved with during the school year.
(You will need to wear uniform as directed)

UNIFORM DAY The Marine Corps JROTC program requires that cadets wear their uniform at least one day a week. The Senior Marine Instructor will establish what day of the week cadets should wear their uniforms. Any time a cadet wears his or her uniform, it should always be worn with pride and care. Cadets must always be careful to be on their best behavior when wearing their uniforms. Improper behavior by cadets is not tolerated at any time and is severely dealt with if in uniform. 

CONDUCT IN UNIFORM Your appearance and conduct should be impeccable while in uniform: Do not chew gum. Do not smoke. Do not walk or stand around with your hands in your pockets. Wear your cover outdoors at all times and remove it indoors. Salute all officers. Greet all cadets and treat everyone with respect. Do not use foul language, tease others, or wrestle/play in uniform.
