Indeed, I'm inclined to agree with much of what has been said. Space Operations Adaptation is not even required for a suit in vacuum, ELS allows for 24 hour operation in any sealed environment such as vacuum etc. I wouldn't bother with mounted weapons, a silenced SMG in the mission equipment pack and an AR in the cockpit or something similar would do the job, you do not want to be engaging enemy armour.
Best way to avoid a fight of course, no be there. Which is why my ground operation suit proposal comes with just 75KG of mission equipment but
3 ground MP + Mechanical jump booster for a running speed of over 40kph. 2 points of standard stealth armour makes it a hard target to hit, especially at these speeds and the extended life support keeps it running for 24 hours in any environment.
If aerial manoeuvres are expected, e.g. for ASF pilots or Mechs in microgravity then the Mechanical booster can be switched for regular jump jets for 2 Jump MP.
