The spys are supposed to out play the mercs with their brains, not sit in a corner with a dismounted turret and mow down anything they see while in armor mode.
literally nothing a Merc can do against that.
Use common sense please.

Nano Suit Attackers > Human Defenders.

Marines Have lasers that give away their position.

They can't move fast.

They cant use armor or cloak or VISOR mode.

And the fact that they have better guns is kind of irrelevant considering I just melle the first guy by sneaking up to him or charging at him with cloak on, kill him, then pick up his awesome weapon, then cloak so they don't see the laser.

i agree all kids do is go to a corner and camp ...
