Emplacements not engaging from larger distance than 200m

Is anybody else experiencing problems with manned emplacements engaging blue team/player from a larger distance than 200-250m? I cannot for the life of me get it work, not even when the bot is set to red alert. Is it the terrain? Is it the (specific type of) emplacement itself? Something completely different?

I had set up several manned emplacements on an elevated terrain, inside houses/windows and inside a sandbag bunker; the window gunner would engage me upon approach at say 250m. The sandbag bunker gunner didn’t shoot at all, even when I stood in front of the bunker. Only when I opened fire, he returned it. Heck, later I even moved the emplacements outside and they still wouldn’t shoot from afar. This didn’t seem to be a problem in Typhoon Rising/Escalation.

I would love to find some clarity on the subject, as I am both puzzled and left with solely CQB stuff on a long distance/sniper mission…

Thanks again all (Captain too so far, appreciate it)
