Get 3 maxims and try not to ever lose them. I find conscripts quite worthless at fighting, and only good for merge and AT nade. Use them to merge your maxims if they drop models, then maybe get 2 guard squads (WITH DP!) and make sure to have an AT gun and AT nades by 6:30 in the game to counter a luchs. Having one or two 120mm mortar also helps a lot.
120mm mortars at 13 popcap is broken. But everything else is good!
My usual build order is:
maxim (x3)
conscript (x2)
AT gun (if fuel isn't cut)
T3
T70
Alternatively, ZSU is good against blobs for suppression, can help if you're being flanked a lot and need mobile suppression against those flanking squads.
You can lose the game if you get medics instead of ZiS gun, for example, so it's important to be aware, but I'm sure you already know that Dullahan.
Basically, the idea is to think of Maxims as the main infantry squads while any traditional infantry squads are there for support.
Also, I'm not aware how players tend to do this, but right clicking maxims to place w/out setting them up can be useful 9/10 times because the maxim will auto face the first target.
With good micro you just suppress, move back, then fire at the volks again.
But having a second or third maxim around to suppress pins squads faster and allows you to suppress more squads as well.
In general, Shock Rifle Frontline is good with this tactic. I had a bunch of replays from December but got patched out
In general I would get 3 SU76s from T3, then just wait for IS2. It may be easier to do this same strat w/ Armored Assault (because of radio intercept), but then you lose the elite, high dps shock troops.
I also like to get a second engineer to put mines everywhere. In front of doors is quite good especially on certain maps with dominant buildings. It's a savage tactic but it can make ppl rage when their first falls squad gets wiped by a TM-35 or even a trip wire flare
