Clip 1 speaks for itself, if those are Volks, Grenadiers, Cons then they don’t wipe everything while taking like 5 mode drops. Riflemen don’t count since they’re offensive minded and are nowhere near as good as Sections on defense.
They would, if they spend similar amount of resources, popcap and commander abilities.
To replicate a similar value, it would be 10 Conscripts squad without 7 man upgrade. Charging with FMR and throwing molotovs. It might not wipe as fast, as with HE nades but they would win that fight nevertheless.
9 Volks, some with STGs, charging with FTF or Valiant Assault.
10 Grenadiers or 8 Grenadiers with 5th man upgrade, charging with Assault and Hold.
I didn't made exhaustive test but i replicated both scenarios on same map.
Two times test: 4 Volks with (only 2) and without STG (none) charging on the right side, with Valiant Assault, charging a Vickers and an IS. They have the same result. The left Volk manage to sneak and throw a grenade and they don't have issues wiping the IS.
For the left test, i went with 5 man upgrade 4 Gren squad and one simple one throwing 2 Rifle nades (cause i couldn't easily replicate the immediately wipe of the MG) at a Vickers and 2 IS. Got similar results when using Assault and Hold.
