The CH252 ranges in weight from about 1.36 kg (size medium) to just over 1.63 kg (extra large). It makes use of the UNSC's MITHRIL armour material which provides increased protection against plasma as well as ballistic weaponry by shattering bullets and disrupting the path of plasma bolts. This is coated with olive-coloured ballistic nylon. It is lighter than the CH127, but is nearly identical in shape to untrained eyes.
