What is a disadvantage of using the stinger in the deck-gun configuration?
It may require the engine apparatus to park in close proximity to the fire to ensure the proper reach and penetration, thus placing the engine in a potentially dangerous position
What is the purpose of the limiter pin?
On the portable monitor it prevents the nozzle from being accidentally rotated too low
