An illustrative embodiment of the barrier-piercing firehose nozzle assemblies may include a nozzle inlet housing having an inlet housing interior. A spray nozzle may be disposed in fluid communication with the inlet housing interior. A barrier-piercing applicator may be disposed in fluid communication with the inlet housing interior. The barrier-piercing applicator may be selectively deployable between a retracted position and an extended position. At least one discharge opening may be provided in the barrier-piercing applicator. A selector valve may be provided in the inlet housing interior. The selector valve may be selectively deployable in a first valve position in which the selector valve is disposed in fluid communication with the spray nozzle and a second valve position in which the selector valve is disposed in fluid communication with the barrier-piercing applicator.
