Re: [gurps] [VEHICLE] of the week 732 ? Land Dreadnought

[Clinton N. Fell]

Another interesting design.  A couple of questions though.  What are the 
IFF and Radar Detector for?  At 3rd edition TL6 radars are still mostly on 
ground stations, Medium and Large bombers, and night fighters.   The 
bombers may be a threat to this, but I'm not sure that passive radar 
detection is the way to go here. 

Why not some additional top armor?  Airborne threats seem to be one of the 
largest weaknesses of this system (the AA will certainly discourage it 
however).  The other standard response to this at TL6 (besides an intrepid 
band of heroes) would be indirect fire Field Artillery.   The turrets can 
probably take a decent hit but the body is a bit thin.  I'm betting an 
88mm or so could do some damage.  Granted indirect fire vs a mobile target 
isn't the best but I would hate to have my nefarious plans disrupted by a 
lucky shot from some schmuck 4 miles away.

And one more thing.  How about two V-2 style rockets launchable from the 
rear section?  Nefarious bad-guys with an agenda would love to be able to 
launch their chemical or biologic agents on unsuspecting cities unless 
their demands are met.  Plus then it would look even more like an Ogre.
