Assault Armor

Assault Armor is a Hybrid mod that adds 25/50 SP/HP to your suit while also replacing dash with a melee attack.

It is unlocked by default.

Tactical Analysis
Assault Armor protects you from some additional damage and gives you a 100 damage close quarters melee hit. The melee does cost fuel, so be wary.

Consider pairing this with a mobility ability, as the lack of a dash means you are noticeably slower than everyone else.
