The Armor of Sahelanthropus was Depleted Uranium, which if the Metallic Archaea was used as the catalyst, The Metal Gear itself is the nuclear weapon. Sure there is its RailGun and it could've fired off nukes like REX and ZEKE, but Sahelanthropus could waltz into enemy territory and activate the self destruct feature. ST-84's armor is weaker than REX's for reasons, Huey states this after Ocelot get's his fun with him.

REX has different armor than ST-84. Listen to the tapes on Sahelanthropus and what Huey and CodeTalker also say about the stuff (Huey talks about his creations and CodeTalker speaks of how Skullface mixes in the Archaea with the Walker Gears and so on for his plans).
