Thanks to one of the players in my area, I have been beaten up by nearly all the canon variants of the Hetzer (stalwart Liao player). Do have to admit that I enjoy it though. It is a vehicle that really gives battletech that OGRE level of fun. It and the Scorpion and Vedette... those three are a blast to go up against.
Stock is always scary in areas where they can hide or corral mechs into cross fires.
The medium laser boat really can ruin a day when running like a pack of piranhas, especially in succession war play.
The LRM boat really makes my day miserable sometimes, especially if he getting spotters from a more standard stock model.
The SRM boat... never works out well except when he is going up against a vehicle force. This might be the luck of the player but it is his least favorite cheap box on wheels.
The LBX version. This is a bane and I enjoy the challenge of going up against one. Really keeps my VTOL and infantry heavy units at bay.
Haven't seen him drive the WoB Protectorate variant... since I do most of the WoB unit driving and I am not a fan of the Hetzer (prefer hover, VTOL, and tracked with all fairness). Perhaps I should pull them out and fire at him for a change. Might be fun, despite not liking RACs much.
Now, there has been a whole slew of custom variants over the years... but those amount to not much to pretty good... depending on the luck and the map that day. But the end result comes down to this... its a good tank for the price and for its role... it comes down to this, if you know how to drive and the tactics behind Assault Guns in most historicals, you can drive the Hetzer.
Your mileage may vary.
