The only height restriction for the military if for Pilots. The existing policy pertaining to the minimun height standard upon enrolment, 152cm, is being reviewed and your height will not effect your application. Should a minimum height standard be required, it must be occupation specific. But that being said, the requirement must be justified and well supported with regards to occupational requirements.
Though I will say that some of the gear, ie ruck sacks, are really much more comfortable if you are taller ot at least average height. For those people on my courses over the years that have been shorter, they find that the ruck sack and even the boots, which are usually smaller the shorter you are, can be uncomfortable and rub in all the wrong places. There were some women I knew who took a size 3 combat boot. These had to be specially ordered.
