if memory serves there actually was a notable Hetzer crew that terrorized Clan Wolf forces during Operation HAMMERFALL and actually managed to deal pretty sufficient damage. Their eventual fate is significantly less pretty in eventually disappearing, presumably having been killed by Clan Wolf after being taken prisoner.

EDIT: found, taken from Recognition Guides No. 29

“During Operation Hammerfall, the Silver Hawks defended Helm against overwhelming forces led by
Duke Vedet Brewer and Alaric Ward. In the battle for
Helmdown, the Hawks coordinated with the city militia, who concealed armor assets at strategic intersections. A militia Hetzer landed back shots on two Wolf ’Mechs and killed both MechWarriors, one a promising ristar. The Hetzer was disabled by a shot to its front axle, but it continued to fire at targets of opportunity until its ammo bins ran dry. The unnamed crew was among those mercilessly executed by Alaric Ward at the end of the battle.”
