The glider part is already fixed in DBP. You can replace officers from the glider, and the glider will self-destruct if it has crash-landed.

I find vet 5 raks OP. But they're not unkillable. Cloaking 75% movespeed with fast RoF. Get lucky they don't hit the dirt and you can wipe things quick. However they still have the issue where all the models bunch up on retreat. So easy wipes for howitzer carries like the bulldozer.

Cloaking movespeed has been nerfed to 50%. While that doesn't sound like a lot, it will prevent raketenwerfers from amassing veterancy through search-and-destroy missions.

They'll still be annoying as hell to use/counter, but that seems to have been their design intent from the very beginning.

Please give your input on what you guys think should be done with USF smoke:

I think it should be fixed nontheless with some modifier, especially if volks will retain an additional weapon slot.

I don't see how this is a problem with Volks. They cost 25 to reinforce, and don't get amazing veterancy bonuses anymore. You also don't routinely see Volks with slots free roaming around, due to the prevalence of the STG upgrade.

Volks new formation (which is a copy-paste of Conscript one) is now also more compact when fully-reinforced to reflect their reinforcement cost.

The IRHT searchlights scan_action is under the unit's sbps file.

The modifier that the scan action applies on reveals units in the FoW, but doesn't allow units to acquire the target.

In order to allow revealed units to be targeted, you would probably want to use something like Command Panther marking (which actually reveals the territory beneath the affected units). Doing so has the potential side-effect of allowing players to target off-maps on revealed units (i.e., it would allow them to bypass FoW requirements).

Regarding (2), I've never tried anything similar. You'd have to experiment with it using IRHT's weapon (which you will find linked under the scan_action

Regarding (3), I'd go with something like Valentine, and an always-on action, or a toggle, or whatever you have in mind. Note that a scan of 360 degrees won't really be useful to the player, since they most likely want the area in front of them scanned (145 degrees), more than anything else. A scanner that rotates the full 360 degrees means that it's not detecting something useful at least 50% of the time (maybe that's the downside you're aiming for?).

Currently, there's a very serious bug regarding IRHT and Valentine. Any infantry unit that retreats while being suppressed at the same time of being scanned has the negative effects (maphax) permanently added of them. I've made multiple attempts to address this, but to no avail.

My recommendation to you is avoid putting severely hampering side-effects to the aura (e.g., making squads easier to hit), due to the potential for the effects stacking permanently.
