SEAL Armor System

The SEAL Armor System is a classification of powered armor, similar to MJOLNIR armor, that the SEAL-IIs use.

Early stages
SPARTAN-C118 once wondered why there was no underwater variant of MJOLNIR armor. In 2550, he joined ONI and recieved funding to create a new batch of super soldiers and powered armor. He envisioned it to work underwater as well as on land. In 2552, his new SEAL-IIs and their new armor were ready for battle.

Helmet
On the exterior, helmets appear very different. However, they all share the same basic functions: They all have an improved HUD that describes oxygen level, an underwater vision filter, and a gold visor.

Chestplate
All SEAL-IIs use the same chestplate variant. It is equipped with oxygen tanks that provide 10 hours of oxygen. The chestplate also features additional pressurization so the wearer can survive at the bottom of the ocean.
