The Muck Chuck came in two varieties: Muck Chuck Original Long Range and, later, the Muck Chuck Close Up.

The long range edition was essentially a catapult, capable of firing a multitude of muck-types distances of up to 1500 feet (457 metres). Depending on the selected ammo, and the chosen spray settings, a variety of results could be achieved:  blindness and vomiting would result from a ‘fine spray’ of dog muck, whereas human muck set on ‘heavy load’ would achieve severe vomiting and often cause a retreat of the enemy.

The Muck Chuck Close Up was launched several years after its predecessor and was born of the increased number of prisoner catchings and desire for punishment. It was essentially a miniature version of the original design, calibrated for maximum efficiency and effectiveness at 20 feet (6 metres); It could pop a stool into a detainee’s mouth without the operator having to so much as look at the target.

Despite the technological advances in weaponry, the Muck Chuck remained in constant employment into the early 20th century, finally being taken out of service due to its futility against air artillery. Muck Chuck Close Up is still occasionally employed today, although only when the forces’ oppositional respect is below factor zero.
