Army lingo

There are some words that I keep hearing in the army and it is seriously annoying the shit out of me. One of them is indented. From food to fans to transport, they just have to use indent for everything. Another word is stores. They call the equipment that we use as stores. Everyday the word stores is just bad news. We would bring them out ( quite heavy ) for either training or only to bring them in again. This is a pain in the ass when I'm trying to get a proper rest in bunk. Lastly the word I dread the most is book in. Instant depression upon hearing this word. FML .
