you need to think more of the grander strategy when fighting against sturmpios imo. ive been using a 2 sturmpio start since WFA was released but ive changed strategies recently.
Against a competent player who knows how to creep up into close range, sturmpios are practically unbeatable in the early game. you basically have to get a lucky crit or hope they reload once they get into close range so you can kill a model. even then its very hard to kill them.
basically you'll want to avoid one squad fighting another sturmpio squad alone. Go to a different part of the map, you'll have numerical superiority to drive the enemy off that side and you'll be able to bleed some manpower.
if you have to fight sturmpios, make sure your squads arent doing it alone (atleast in the early game). focus firing sturmpios will make short work of them, especially if theyre charging, and losing 2-3 sturmpio models is a huge blow in the early game. its a huge manpower bleed especially when the timings of the trucks is key.

if the opponent chooses 2 sturmpios in the beginning, you can deal huge manpower bleed in the mid-late game. as long as you continuously kill of a few models from each squad whenever you see them using focus fire, you can delay a lot of important units for the OKW

faust and nade are two really important abilities imo. also i think all these fragile-small squad size units are supposed to used more ambush style, hiding them behind LoS blockers near strategic points to ambush individual squads.
fallschirmjager, JLI, and sturmpios all come to mind that excel at these tasks. their individual medium/close range firepower is really impressive and can take on most squads in close quarters if they have the element of usrprise

Heres one guide i made that uses an aggressive 2 sturm pio start. works better in 2v2s but also works in 1v1. requires you to be very smart about positioning and using your sturms effectively.

right now im using a modified order of that build that is a little bit safer where i skip out on the 2nd sturm and go jaeger light infantry when i need them.

personally i very rarely go MGs because theres a certain risk in using them. same reason why i dont like using the half track that much.

im not saying i won because of my JLI, but they did have good impact. my first squad killed 14 men, second to my 15 kills on the sturmpio squad. the second squad killed 6 right off the bat before the game ended

Is it intentional that the OKW truck hitbox blocks grenade throws? You cant throw grenades through/over the truck which seems odd as you can throw grenades through/over buildings and hedges.
the grenade just gets caught on the side of the truck and explodes instead going over to the other side.
