Don't IR Obers ignore most of the RA cover bonusses?
If that is the case: why do you base half your argument on that? IR Obers are doing their job as intended: Shred infantry in cover and close range. Almost every unit would lose against them when moving in. That's not an issue with rangers, but the general abundancy of cover in team games due to late game arty. Alternatively, that's an issue with the IR StGs, but I'd highly doubt that.

My point is not Rangers vs Obers. My point is:
Rangers are doctrinal (2 doctrines)
Similarly priced Obers are stock.
Obers need less muni investing, have 2 types of nades, cost less, have suppressing fire and booby trap.
Comparing the combat is not the point. I used the combat to just give a general insight how two elite squads duel it out in possible teamgame scenarios. One point could be that obers with IR are OP in close to medium range but that's not something I'd want to argue now because I don't think they are (maybe, really don't know or care).
Rangers cost more MP, pop whilst having poorer combat and utility skills. Only real use for them is on CQC maps with lots of sight blockers because tommy rangers need to run in.
So I'm arguing that rangers need something. Anything. The DMG reduction would be preferable, as some say, but won't bother analyzing potential problems as I don't care enough. Just pointed out how Obers win most of the engagements (and how the IR obers are the strongest ones in any scenario, but they are also doctrinal so it's fine).
