Then is it 40 fuel advantage over the 1st cromwell, not counting UKF side upgrades. I never lost a stug vs a bofor and I never say outrange.
First you damage the bofor with a mortar, force him to brace, wait 20 sec and then attack with a stug supported with infantry, spreak to not get them shred in one shot. The stug is more than enough to take a 70% life bofor. Hell, you can also smoke the bofor and attack ground with the stug from mid range if you want to make it safer!
his emplacements are virtually untouchable until you got the stug up. That's a long time to just leave him alone.
A mortar emplacement can easily deal with most mortar attack, or the bofor can just use its barrage ability. Even just one atg will repel any armor attack.
yes, it's a huge investment, but that investment will lock down a huge portion of a 2v2 map. You can conceivably cap around a sim city on a 3v3 or 4v4 map, but not a 2v2 map.
