In a nurse tanker operation without a shuttle, identify how the MWS apparatus could supply the attack apparatus.

• A. Use a discharge line from the pump of the nurse tanker to the attack apparatus
• B. The attack apparatus drafts directly from the nurse tanker's internal tank
• C. Both of the above
• D. Use a portable water supply from the MWS tank

Answer: (C)

When you don’t have a shuttle between the nurse tanker and the attack apparatus, the MWS system can still deliver water by two straightforward methods that use the nurse tanker directly. First, you can run a discharge line from the nurse tanker’s pump to the attack apparatus. The nurse tanker’s pump provides the pressure to push water through the hose into the attack engine, so the attack apparatus can begin stream flow without waiting for a shuttle. This is a direct, pressurized supply that leverages the pump’s capability. Second, the attack apparatus can draft directly from the nurse tanker’s internal tank. The attack engine would set up a suction line and prime to pull water from the nurse tanker’s onboard tank. This relies on proper priming and a suitable suction arrangement, but it lets the attack apparatus draw water without needing a separate source or shuttle. Both methods accomplish feeding the attack apparatus without a shuttle, which is why they’re both valid in this scenario. Using a portable water supply from the MWS tank is a separate option that could supplement or replace the nurse tanker source in other setups, but the question focuses on the two direct ways water can be supplied from the nurse tanker itself.
