Which of the following weapons can be found onboard Tactical Boats?

The answer is B, which includes the M9, M16, M14, Shotgun, and M203 as weapons that can be found onboard Tactical Boats. This selection is correct because Tactical Boats are equipped for various operations that often require a range of firearms to meet diverse mission needs, including personnel protection, boarding operations, and close-quarter combat situations.

The M9 pistol is a reliable sidearm for close engagements, while the M16 and M14 rifles offer versatility for different ranges and scenarios; the M16 is particularly suited for automatic and semi-automatic fire, being effective in a range of combat situations. The shotgun provides a unique capability for breaching and close-quarters engagements, allowing operators to deal with threats at very short distances. Additionally, the M203 grenade launcher can be mounted on rifles like the M16 or M4, providing explosive firepower for specific scenarios aboard tactical vessels.

This combination of weapons aboard Tactical Boats ensures that personnel are well-equipped to handle a wide array of threats they might encounter during operations on and around the water, highlighting the importance of having a comprehensive arsenal for effective mission execution.
