I wasn't initially sympathetic to the idea that was a problem here, as Wehr have had small squad sizes all the way back to CoH1. CoH2 was just keeping with the established standard that had already worked, so there shouldn't be a problem.
But now it occurs to me that there may well be a problem because of the changes to the veterancy system. Where in CoH1 it wasn't such a big deal to have a squad wiped, because their veterancy was attached to base upgrades, now it's a much more significant issue. In CoH1, your newly built squad would have the vet you have upgraded for its type, but now it's all lost.
In this light, maybe continuing the the 6:4 balance in squad sizes that CoH1 established isn't such a good idea. But I'm not sure exactly what else to suggest doing. It was obviously intended to create the thematic effect of the Germans being outnumbered, and this would be lost if grens and pgrens went up to 5 men. Changing all the squads so the relationship is 8:6 would likely work, but it would be a major overhaul. IIRC, the Eastern Front mod for CoH1 had some 8 man squads, and it didn't seem to change things hugely, but it would still be a big deal.
HOLY FUCK NO, DO NOT DO THIS EVER
LOOK AT THE ONE-SHOTTING WE HAD TO DEAL WITH BECAUSE 6-MAN SQUADS WOULDN'T ALWAYS FIT ONTO COVER
GAZE UPON THE BLOOD AND CRAWLER-SOAKED GROUND
Unless we change like every map also to do this. Then I'd be fine with it. But I'd also be certain that's why they won't.
