Comedy military movie about young guys in the barracks
I'm looking for a comedy military movie about a group of young guys who end up in the barracks. The protagonist lies and says “A prostitute gives you a second round for free”. He kept a diary and wrote that his best friend was most likely gay because he never talks about women.
I only remember a few lines of dialogue "You gave him full points for going back to Mom and Dad”
It’s not Full Metal Jacket definitely - the name was related to the fort where they were staying.
Thank you in advance.
