The NAM Tower Shield is a tool developed for use by existing and future SMDIoN power armors. It was developed initially for the NAM Terratech Heavy Assault Armorsuit - "Devastator" in YE 36 but is usable by any Nepleslian power armor. After much research, NAM finalized the shield into a rectangular shape that curves slightly inwards to allow kinetic rounds to deflect off.

The shield itself is made of a Durandium Alloy frame with Nerimium armor plates added to the frame. The frame and armor plates are then coated with energy-absorbing nano and heat-resistant paint. This combination is the best that NAM can provide in terms of mobile protection. The shield is attached to a power armor's left arm by magnetic clamp. On the clamp is a 360 degree rotary unit to allow the Marine to adjust the shield's facing.

Being Nepleslians, NAM further added a small holster for a VBCS knife as well as a three-barreled 30mm chaingun to the bottom of the shield. Since the chaingun is invisible when the shield is planted, the Marine inside can quickly lift up the shield, point his arm towards the enemy and fire away.
