unless that issue turned up in an earlier revision than 667, I cannot confirm this. I tested it and it seems to work just fine.
[VehicleTypes] 102=HOWI3
[HOWI3]:[MTNK] UIName=NOSTR:Howitzer III Image=MTNK Cost=350 Primary=RadBeamWeapon_2
With this code, the unit has all the basic Grizzly characteristics but uses the apoc's voxel, costs 350 credits, fires my custom RadBeam weapon etc.
