Yeah I went ahead and tried out that strategy, I liked the fact that I had 4 squads with shreks. Still gotta be careful though because of the Sherman tanks using HE. However I built 2 raketenwerfers and tried to position them carefully and I was getting good results with them. Especially if I tried to bait a Sherman to come after my Volks.
I played a game yesterday and one of the allied players had an endless supply of Shermans and Easy 8s. I had a Jagdpanzer IV and 3 shrek squads but I just couldn't handle the sheer numbers of tanks that were on the field. I ended up loosing my Jadgpanzer IV to a swarm and my volk squads were getting hammered by priests. I did manage to field a JadgTiger but it had limited success, it seemed like I should have built Panthers instead of just one big tank.
OH NO...
dont go for jagdtigers against medium tank spam EVER. you're BEGGING to get swarmed,especially in teamgames. Jagdtiger is for IS2s and ISU152.
Special Operations allows you to get tons of AI mileage out of your volks with Infiltration nades(you can counter any allied inf in a 1v1 engagement with a well thrown infiltration assault even shocks), and you can then use the command panther instead of teching to T4.
So basically 4 volks mechanized truck convert fuel to muni,then spam shreks shreks and mines,battlegroup HQ,Convert muni to fuel,and then wait for Command panther.
if you absoulutely need meds just drop with sturmpios.
go for JP4 if you dont have enough time or CP's to wait for a command panther. Both are the best MEDIUM TD/tank hunters in the game when used properly.
