One or two mortars in green cover, halftrack between them for reinforcing and once your barrage gets to cooldown, use attack ground order
ohh I really like this idea. Though the half track is vulnerable to the mortars as well.
My own experience with british emplacements is using mostly the mortar halftracks. Honestly the flame helps but it isnt the end all be all of countering. Dont get me wrong it works and I use it but I use it as a piece of the puzzle. I try to flame the emplacement and use shift click to queue up an immediate move to a different position to avoid initial bombardment then I use either attack ground or barrage to keep hitting it constantly. The flame is good but constant mortar shells seem to do more damage. Anytime they target your mortar you HAVE to move it. the Wehr mortars and halftrack cant withstand the damage before the emplacement goes down. Now I typically only play 4v4 with some friends but in these it usually is that there is always some place emplacements go up, I either try to kill them in a focused manner to prevent a snowball sim city or I ignore the area entirely and set up a back defensive line just to hold back any pushes on that side.
With the advanced emplacement regiment I have found the earlier you kill emplacements the less of a pain they are because they wont be able to get the auto repair yet. ( also found out last night they have to upgrade the auto repair on a per forward assembly basis, making killing these even more valuable).
Even if your mortars cant kill the emplacement you have to keep hitting it because if they dont have the auto repair that means they are repairing it with infantry and they die very easily when repairing to mortars which still costs the enemy manpower and time.
wow I typed way more than I had originally intended...
