Shock vs VSL

Went with engi/clown car into x3 penals. I was feeling him out to see where his MG was, after seeing Grens everywhere I assumed he MG skipped. We fight back and forth with mostly even trades. I am leaning towards Soviet Shock since he is going so infantry heavy, mother russia will allow me to push him back.
He keeps spamming rifle nades which I due a decent enough job of getting out of the way. I push for his gas and in a moment of looking away he rifle nades a penal squad for a wipe. Not cool, I am also mindful of a possible scout car but he never makes it so my infantry stay at full strength. As I attempt to cap upper right side of map he surprises me with Storm camo tactical assault which drops several models before I get away. I chase him away with my shock trooper, we go back and forth a bit and he eventually kills my scout car with his at gun. However around the same time I get a Gren wipe, finally something positive. We skirmish back and forth and I happen to find his AT gun, all that muni I have been saving is about to pay off. I use "For Mother Russia" rush his At gun and get the kill, his camo Sturm trooper gets revealed and wiped while another Gren on the other side of the map gets wiped while I lose an engi squad.
Game has heavily swung my way, steal the AT gun and pretty much heal and hold on reinforcing to get my KV1 out in case his tank is on the way. Feel him out with the KV1, notice he hasn't made a tank but does have another AT gun. I pull back for repairs while attacking other areas with FMR to scare him off and let me get map control. He gets Brumbar out and wipes a Shock squad for trying to kill his AT gun. I scare off his infantry with the rest of mine before he attempts to attack my KV1. He must not have seen Pak shooting and missing him so he moves in close, get beat up by KV1 and pak. I chase his brum down and get the kill.

The Brumbarr was a great idea except he lost to much to quickly before it came in. Since he knew I had KV1 I feel like he should have made Panther instead to keep my KV1 zoned out and used MP on more infantry squads to screen for Panther.
