I can't remember who mentioned this, and upon playing I noticed this as well, but you can no longer manually pick off specific units in enemy squads. It was a way too give you more control over your sniper in CoH1 by targeting the gunner of an MG squad or the stray rifleman while they capped a point (to keep your sniper at maximum distance). I hope it's just an oversight and that Relic can restore the feature. Unless someone can provide a valid explanation to the change, I don't think removing control like this is a good way to go.
It looks like they removed the tag that allowed weapons to fire at individual targets...meaning it's unlikely to make a return.
That's a more serious mistake than it sounds, whether a Sniper will decide to randomly target the MG gunner is a huge deal.
