If you really want to beat Shock Troops with CoH1 units, go for the Stormtroopers with 150 Mun for double StG Upgrade. Quad StG Stormtroopers were unrivaled in their infantry-killing ability, nothing beat them. They also had 90 health when the median was closer to 60, and their armour ontop of that protected them further (it was not the armour we have in CoH2, it was much more sophisticated).
I have no doubt they'd tear Shock Troops to pieces, they were literally the Übermensch.
