Infantry Defense Against Tank Assaults In Red Victory?

[gamerguy]

Hey all, a Squad Battles noob here with two questions about infantry defending against tank assaults in Red Victory:

1. Can infantry in covered terrain (i.e. villages or trees) put up any sort of defense against assaulting tanks?

2. How do single use weapons like the Panzerfaust 30 actually work in game, and can they be effective?

Reason I ask is because of the experience I'm having playing the Germans in scenario 8, Peiper at Jeremjewka.  In nutshell while defending Jeremejewka against the Soviets my Panzergrenadiers were able to Pin or Demoralize all of the attacking Soviet infantry, but many of the attacking T-34's just kept coming and rolled over several of my (at or close to full strength, not Pinned/Demoralized/Disrupted, Morale A) squads in covered terrain with very little difficulty - the only defenders that have lasted longer than one assault have been multiple squads in Town hexes, and even they've been losing 8 or so guys per assault.  A few of the T-34's have become Immobilized, but that's it for tank casualties and I'm not even sure if it was the defenders or the terrain which accomplished that.

Regarding the Panzerfaust 30's, I see mine have both a Fire Value (which varies from 0-3) and a Strength of 1.  Per the manual the Strength of 1 means I get to use this Single Use Weapon once, so is the changing Fire Value irrelevant, or does it somehow represent how many Panzerfaust shots I can get off in a single "volley" fire?  Additionally I've also tried four flank shots against T-34's at range 1 (the max for the PF 30) with good order squads and gotten no kills so far- is this normal, have I just had bad luck or am I somehow misusing the Panzerfausts?  (i.e. instead of actually firing them at enemy tanks, should my squads be holding onto them to somehow better defend against those killer tank assaults?)

Any clarification that a SB veteran could send along would be greatly appreciated - so far my buddy and I have been really enjoying RV, which seems to get infantry combat right enough, but suddenly seeing unescorted Soviet tanks blitzing over elite troops hunkered down in a town has struck us both as being jarringly ahistorical.  Cheers!
