The list of things one infantry section can do is completely comical at this point.
That list is grasping. Nobody in their right mind would equip them with PIATs. Any infantry can benefit from commander buffs, for all factions, there is nothing (anymore) that specifically or permanently buffs IS. Yes they can build caches, but nobody wants to sacrifice the valuable time of their mainline infantry for that. They're also lacking one of the most important abilities of a mainline infantry, which is a snare.
I'm not a fan of buffing the side tech costs either, but to state that IS have a "comically" long list of utility is simply false. Compared to other mainlines such as Volks, and with the fact in mind that they are more integral to the faction than most other mainlines, it is not that special.
Make the UC the 'detection' unit, similar to OKW's Kubel, move construction to REs,
The UC already has stealth detection, but against 18 range faust Grens it is simply not viable to use it in that role against snipers or camo Grens. Construction of caches has already been added to REs.
And as much as we'd like to we can not overhaul Bolster, as Relic will not allow any such major changes anymore.
