Foam Truck

Evil henchmen with their HISS tank.

They also have this vehicle, the Matchbox Hardnose.

It is an airport rescue vehicle, a fire truck designed to spray foam on burning planes.

Matchbox has issued it several times in a bunch of versions.

This on is an InGen vehicle.

It has tanks in the center and a nozzle on the front top.

Presumably the truck is designed to spray stuff and it does not have to be airport fire suppression foam.

So maybe soap and water to wash the dirty dinosaurs.

Or maybe other chemicals of a more nefarious nature.
