police officers is a total 180 from the military. as an officer you have chance for promotion without total humiliation first. military you need to be ready for round the clock harassment (including sexual harassment), holding back from saying anything about it because if you do you are seen as a trouble maker and will not advance. you need to be prepared for hazing which often includes violence and sometimes raping female military officers.
find yourself someone who was in the military and ask them. if you dont mind being told what to do and how to do it every single day; and if you dont mind being sexually harassed and raped; and if you dont mind taking twice as long to move up the ranks as men: go for it. but if any of those things bother you, think twice. a lot of people think women have won our equality but thats not true, especially not in the military.
