Unit x3/ Fire engine / Fire Engine

"Unit x3" is a fire engine that used the modularization design techniques,
integrated the minitype pumper into the bigger one.
At the scene of we have not confirmed

minitype pumper is the first to enter
the fire scene to find fire and
explosive materials, and to stamp

So as to reduce the unnecessary
casualties of firemen.
