Sexual harassment is treated under the umbrella of harassment. There isn't a separate process.
However, when that element of sexual harassment comes into play, it certainly depends on the nature of the complaint. If it's a comment, that will be treated much quicker and in a different way than, say, if there was actually a physical element to it, and involved further parties, such as the military police. It completely depends on the severity and the nature, and even to the extent of who is involved, how quickly the complaint would be addressed.
