Ideas for armor modifications campaign

So I had an idea for an armor modification this modification increases how much damage the master chief does when he hit an enemy also it increases your movement speed when carrying a turret this modification is like the shield modification it’s always active you do not need to switch out your grappling hook, drop wall, thrusters, or proximity sensor to use this modification obviously you use armor cores to upgrade it the first three increases your melee damage the last two increases your movement speed while carrying turrets this is the only one I thought of so far but I’m trying to think of more armor modifications I would put in the game
