Marine Artillery currently employs which type of howitzer?

The M777 155mm towed howitzer is the correct answer because it represents the most advanced and current artillery piece used by the Marine Corps. Developed as a lightweight, towed howitzer, the M777 offers significant advantages in terms of mobility and firepower. It is capable of firing a variety of rounds including the GPS-guided Excalibur artillery round, which enhances precision and effectiveness on the battlefield.

The M777 utilizes advanced materials and technology, making it lighter and more deployable compared to older models, which allows for improved operational flexibility and rapid positioning in combat scenarios. Furthermore, the M777's modern design facilitates easy transportation by helicopters or vehicles, enhancing logistics and support for deployed forces.

In contrast, the other choices—such as the M101 105mm and M198 155mm howitzers—are older models that have largely been phased out in favor of more contemporary systems like the M777. The M110 8-inch howitzer is also an outdated piece of artillery that is no longer in active service with the Marine Corps. Thus, the M777 is clearly the current standard in Marine artillery units.
