these nasty shoulder mounted beasts are fed an alarmingly dangerous amount of fangoes and erupt caustic doom from afar with a violent vomity vengeance! fangoes are horrifying fruit that grow in small bunches on man-eating trees. luckily, the large yellow thrucks are not mere men and can pick these demonic fruits with impunity and use them to equip their shoulder mounted squadrons with their terrifying ammunition.
here we can also see the traditional thruck form of war decoration, where a gold studded iron nail is driven into the thrucks shoulder. this particular thruck is quite notorious and has been awarded enough shoulder spikes to equate at least 8 successful missions.
as for the hellbeltcher itself, it is usually made from an iron-bellied regurgitater. these lizards are usually held in place with splints and other bondage and affixed with a crude glass scope. regurgitaters are so sturdy that they can go for months under these horrible circumstances; being constantly crammed with noxious fangoes and bombarding bone-headed beasts with bulimia!
cover your heads and flee friends! else the hellbeltchers will claim another disgusting and slimy victory!
