I didn't use it because don't know how to use it or how effective it is. I used on some bridge maps but it shouldn't be counted, didn't it?
It's not supposed to be entirely defensive, unlike the name "Emplacement" presents itself.The OBR should be used in an aggressive role. By building it near the front line, you can buff out Paks, weapon crews, bunkers, FHQs, etc. You should use it to bombard the enemy defenses and infantry in heavy cover.
I tryed it in 1o1s 500vps vs a good PlayerIts useless, if it would be moveabel like a morter it would be great
