The Snotling Pump Wagon is very much like a chariot in that it consists of a wooden fighting platform, rather like a ramshackle wooden hut on wheels, and it moves under its own power. In the case of the Pump Wagon this power is provided not by horses, wolves or some other beast, but by the frantic pumping of Snotlings which drives a simple mechanism and keeps the Pump Wagon moving. The Pump Wagon is also equipped with a spiked roller at the front, which crushes and pierces any foes (and Snotling crew) unfortunate enough to fall beneath it.

The rules described for chariots apply to the Pump Wagon as well with a few exceptions which take into account its unusual construction and crew. As the Pump Wagon has no horses pulling it any hits must be distributed amongst the crew or machine only, as shown on the chart below.

The Pump Wagon is heavily constructed and has the same basic profile as a chariot. This is shown here again for convenience. Like a chariot the Pump Wagon causes a great deal of damage as it charges but the effect is even more extreme due to the destructive power of the crunching roller at the front.

The speed of a Pump Wagon tends to be somewhat unpredictable as its crew are continually squabbling over which of them is going to operate the pump. An enthusiastic Snotling will fight his way forward and pump like crazy for a while until he is completely exhausted when another will shove him aside and take over. This means the machine tends to go forward in fits and starts, sometimes quite quickly but at other times embarrassingly slowly.

Because the machine's speed is reliant upon the whim of its rather dim-witted crew, the player has little choice over its speed at all. To represent this the Pump Wagon has no fixed move rate. It automatically moves 2D6" and is moved along with compulsory movement before other troops can move.

The player can control the direction which the machine moves in, representing the efforts of its crew to steer the thing by leaning precariously to one side or the other, but he has no say over the speed. If the machine's speed is sufficient to bring it into contact with a target then it is considered to have charged. No formal declaration of charge is necessary. The target may make the usual response just as if it had been charged in the normal manner.

It sometimes happens that the Pump Wagon's move means it has to traverse terrain which it cannot cross. For example it might be forced into a river, bog or straight through a wall. In these situations the Pump Wagon sustains D6 strength 6 hits due to damage sustained as it crunches and smashes its way through.

It can also happen that a Pump Wagon is obliged to move into friendly troops, although this is rare as you can move the machine as you wish. A foolish general might surround his Pump Wagon with friendly units only to see the machine crunch through his own lines in the first turn! When this happens work out the effect just as if it were an enemy unit. Even the Snotlings will fight as they are far too excited to care what they are doing. The Pump Wagon does not abandon the fight until the combat is complete and one side broken or destroyed.

A Pump Wagon is dependent on its crew for mobility, so once its crew are all slain it cannot move. It does not rampage around like a chariot for example. The model may be removed once the crew are slain, as it is of no further value.
