HUD

From Command and Conquer Wiki

A HUD (Head's Up Display) is an integral piece of technology on the modern battlefield. First untroduced in the First Tiberium War in the form of portable EVA units and overlays inside appropriately designed helmets, it provided the user with battlefield information and objective tracking updated in real time, the approximate levels of his or hers health and armor and even a radar. The technology has been upgraded and in use ever since.
