Energy shield test station

Summary
In the level Armory after you get your sight checked the Marine will tell you to stand on the red square. If you stand on the red square he will say to put your hand on the red touch pad. After he says to put your hand on it walk over to him. From behind his control desk you can press the button. You can even walk around while he says, "Bingo! As you can see..." It won't help you in your game play at all.

You can also find two carts also in the room, and push them into the red square. If the boxes are centered more than you are, you will be pushed out of the square.
