Regarding effectiveness, I've never seen a flak truck wipe out a squad as it walks into it's line of sight, I consistently lose my scout cars from just crossing into the Bofors line of fire. Seriously, it kills light vehicles before they can even reverse, sometimes squads before they can retreat and god forbid you ever have to retreat through a bofors line of fire. We all understand that wiping squads out is one of the fastest way to get ahead in the game and the efficency in which the bofors wipes squads/light vehicles is amazing (for lack of a better word).
If my flak truck was my t1 building, only costed 50 feul and immediately ripped apart anything walking into it's sight, I would be willing to compare the two.
That is the point. A Bofors behind a shotblock will wipe your squad 80% of the time because when you see it it is way too late. Every shot kills at least a model and retreating doesn't help.
You could call a Mortar + Bofors somehow a good mix of units but the Bofors is a mortar itself what is ridiculous. I know the range is not as far as the mortar's one but it is simply bullshit. A mortar pit with a bofors and a command point together with the emplacements commander is just dumb and requires 0 micro to build but an extreme amount of micro to fight it.
The emplacements are extremely durable and got even free repairs! How ridiculous is that?
You build three buildings with your pioneers and lock down a huge area of the map without ANY further micro effort. While the Germans have to move their mortars/LeIGs after each barrage and still are not able to kill anyhting.
Meanwhile the Brit can take the map and micro other units while also making a cup of tea. That is no joke. I once watched someone play Brits 2v2 on Bahnhof Ettelbrück and after about 10 minutes he went to the toilet. After about 2 minutes he came back and his mate still managed to cap the map even further and his Mortar Pit was getting Vet 2 near 3.
