In MS Paint there will be a rectangle tool.

Tough war, that one. Semper Fidelis.
Terminal Lance - Terminal Lance #157 “War and Peace”
The military is one of those things you join with a purpose. I don’t believe I could possibly know or understand every reason people embark on such a life-altering event, but I know one thing: I joined to go to war. In 2006, the war was in full swing and I wanted a part of it. It goes without saying, then, that I have no idea what the Marine Corps is like in peacetime. In my head, it’s something like Heartbreak Ridge meets everything I...
