I think the problem is the randomness of the SASL, which could be considered its strength normally (true fog of war for an omniescent player).
Also, maybe it's because I've only ever played Germans. The Command rule almost requires kill stacks, which easily handle most single/maybe a couple of EN MMC that have to brave the open ground to approach a VPO/objective, etc. The EN tend to come piecemeal and are easily dealt with generally.
Having said that, there are circumstances when the RNG (i.e. the die rolls) go against you and you can be easily overwhelmed. E.g. a pair of KV 2's roll up and you only have ATR's to deal with...or the EN gets three artillery strikes to hammer you into the ground, literally. It seems to be an either or case in my experience. Either its a cakewalk, or you are chased off the board with your tail between your legs to save what's left of your company.
Not sure how to fix that, but one thing I've been doing lately is ignoring the EN action rolls, except to check for PANIC. If they pass the PANIC check, I move them in what seems their best interest. But again, they come piecemeal and are generally easy to deal with. Now I'm generally playing against weak troops, 527's and 426's, but I'm sure the deal might be different in say Festung Budapest with 458. etc.
I’m fairly new to SASL and have been playing this campaign as well. I’m on mission 7 and am +5 on the campaign.
Would like to know how the Pursuit mission went for you and what you did to win.
