Then keep going 5 gren BO and keep wondering why you can't win against rifles and M15.
Please stop. Don't comment on 1v1 gameplay if you are going to be this clueless. A 5 minute Pak40 is just not feasible in 1v1.
Here is how USF vs Ostheer playes out if ostheer goes for 5 minute pak:
- USF gets 3 rifles
- Ostheer gets something along the lines of 2 grens 1 mg42.
At this point Ostheer is at a minor disadvantage in terms of firepower. Rifles are considerably more potent than vanilla grens. You have to get lucky and get a double suppress on the riflemen or you'll likely not be able to take more than 40% of the map.
Next step:
- USF gets lieutendent, then gets a AA halftrack.
- Ostheer techs up to BP1, gets T2, builds a Pak.
Now the Ostheer loses. Ostheer has 2 gren squads, a mg42 and a pio squad to deal with 3 rifles, a heavily armed lieutendent squad and a AA halftrack. USF doesn't even need to use the AA HT at this point, 3 rifles and a lieutendent are more than enough to crush the 3 T1 ostheer squads. And manpower wise the USF will have enough mp for a quick 50cal HMG follow before the ostheer can get a 4th infantry squad. Bye-Bye map control, hello basepin and have fun waiting it out till the shermans roll in to finish you off.
Out of all the suggestions made to counter the 5 minute AA halftrack, yours is the worst.
