After closing the breech and aligning Breech Witness Marks and hearing STAND BY, Cannoneer #2 primes the howitzer using the __________.

Explanation:
Priming the howitzer is the step that places the percussion primer into the breech so ignition can occur when the firing command is given. After the breech is closed and the witness marks are aligned, the cannoneer uses the primer feed mechanism lever to feed and seat a primer into the breech chamber. This lever is built for delivering the primer from the supply into the breech in the correct orientation so the firing pin can strike it reliably. The safety latch is a separate safety device and does not perform priming. The muzzle brake is there to help control recoil and isn’t part of the firing sequence. The elevation handwheel adjusts aim, not priming. So the primer feed mechanism lever is the correct tool for priming.
