 I'm a Master of Surface Warfare Engineer in Warfare, Brett Lugini, CrewServe Weapons Instructor, onboard the guided missile destroyer USS Jason Dunham. We're currently operating in the fifth fleet area of operations here to support maritime security and stability in the Central region. Today we're out here qualifying some of our personnel on the CrewServe Weapons to include the M240 machine gun and the M2HB 50 caliber machine gun. The purpose of these weapons systems is self-defence of the ship. We use them in our everyday operations to defend against any threats or would-be adversaries we have come our way. Or if we're conducting a straight transit, moving through a choke point, we'll have our SCAT team manned up, providing 360-degree security for the ship. 50 cal, we've got several of them mounted around the ship. You can realistically reach out to a one nautical mile, effectively engage a target, which is pretty good when you're trying to defend a ship from a further distance. It gives us that time and opportunity to classify the threat and engage the threat as necessary. M240 Bravo, it's a 7.62 millimeter machine gun. Slider to carry, we can implement it on the go. We tend to use it as a roving machine gun so we can set a gunner up and have them anywhere they can find stable support. So when we're teaching sailors, we'll qualify them on the CrewServe Weapons. We're trying to make sure they're sufficient on all aspects of the weapon. So we start them off with trigger control, firing one round, two round, three round, rhythm shooting short, short, long, and get them proficient at reloading the weapon. And throughout the process, we go through a couple different fundamentals we teach them about remedial and immediate action if something breaks or runs out of ammo if there's an issue. We want them to know how to get the weapon system back up and get them back in the fight. We try to train our sailors to employ their weapon to the best of their ability because you never know when something is going to happen, whether they're asleep in their racks or if we're going through a choke point. They have to be ready 24-7.
