The aircraft carrier

You sneak around on board to the shipping container, where you shuffle around hastily to the side the doors are on. You attempt to open the door, but with a great deal of complaining, an awful screeching noise as the hinges move and you open one of the container doors, which is surprisingly unlocked. You made too much of a din though, as a guard rushes over with a curious grunt. He was too late, as you slip inside and close the door before he sees.
Inside is a strange metal humanoid figure, about 6 feet tall, with big arms extending to the shins of the stubby, 2 foot long legs, the thighs are one foot each and the shins are of the same length. The thing is mostly burnt umber, and no apparent head. But on closer inspection, you see a small glass stud which could only be the "head." The whole front of the body appears to be a panel, but you can't tell for sure as the figure is lying down inside the container.
The guard is not dumb however, and you soon see the beam of a flashlight as he enters the container. You only think to try and open up the panel, and you accidently press somewhere on said panel and it hisses open, you clamber inside instinctively and the panel closes. But the guard doesn't notice. As you make yourself comfortable in a sitting position inside the body of the humanoid, you hear a humming from inside the thing and consecutively following it, a rapid, high pitched beeping that stops just as your start to get irritated by it. The guard hears none of this and makes a few circles inside of the container before leaving.
