When making a windage adjustment on iron sight, rotating the knob clockwise will move the strike of the bullet to the right. This is because windage refers to the horizontal adjustment of the sight to compensate for the wind's effect on the bullet's trajectory. By rotating the knob clockwise, the sight is moved to the right, aligning the bullet's path accordingly.

This gauge is specifically designed to measure the wear and tear on the muzzle and breech bores of the gun's barrel. It helps determine if the barrel is still within acceptable limits and if any maintenance or replacement is necessary. The other options mentioned, such as the barrel wear gauge, pre-embarkation gauge, and chamber and barrel assembly gauge, are not specifically designed for inspecting barrel erosion in the M240B machine gun.

111. You must replace the barrel of the M9 pistol if you find pitting in the bore area that exceeds

Two lands in width and 1/8 inch in length.

Two lands in width and 3/8 inch in length.

One land in width and 3/8 inch in length.

One land in width and 1/8 inch in length.

If pitting in the bore area of the M9 pistol exceeds one land in width and 3/8 inch in length, it is necessary to replace the barrel. This indicates that the pitting is significant enough to affect the performance and safety of the pistol. Pitting refers to the formation of small holes or depressions on the surface of the barrel, which can weaken its structure and potentially cause malfunctions or accidents. Therefore, replacing the barrel is the appropriate course of action in this situation.

If pitting in the bore area of the M9 pistol exceeds one land in width and 3/8 inch in length, it is necessary to replace the barrel. This indicates that the pitting is significant enough to affect the performance and safety of the pistol.

112. Which of the eight steps in the cycle of operations for the M203 grenade launcher occur at the exact same time?

Extracting and ejecting.

Extracting and cocking.

Unlocking and cocking.

Loading and chambering.

The correct answer is "Extracting and cocking." In the cycle of operations for the M203 grenade launcher, extracting refers to removing the spent cartridge case from the chamber, while cocking refers to preparing the weapon for firing by pulling back the cocking lever. These two steps occur simultaneously, as the extraction of the spent cartridge case and the cocking of the weapon are interconnected actions that happen in one continuous motion.
