A portable ground standing fire fighting monitor includes a support platform intended to be placed horizontally on the ground surface, a water gun with a curved flexible inlet tube having an inlet end and a curved discharge head having an outlet end, a watertight ball-bearing swivel joint coupling the discharge head to the curved flexible inlet tube, and an adjustable bracket assembly, a crank wheel, and a threaded rod and ball joint connector coupling the flexible inlet tube on the support platform. By rotating the crank wheel and the threaded rod and ball joint connector therewith, relative to the bracket assembly and flexible inlet tube, the flexible inlet tube and discharge head therewith can be adjusted to varying inclinations thereby allowing the operator to adjust stream flow direction vertically. By pivoting a swivel handle connected to the discharge head adjacent to the swivel joint, the discharge head can be swivelled from side to side thereby allowing the operator to adjust stream flow direction horizontally.
