 Land navigation actually still serves a practical purpose even in this day and age. You never know when equipment is going to go down or when the fastest way to find something is going to be your ability to use some old-fashioned equipment like a map and a compass or even basic terrain association. I'm senior and drone starter gunnery sergeant Pettus. I work with Alpha Company first recruit training battalion and right now we're out here. We're on track with Papa Company one of their series in the land navigation course. We give them the opportunity here in the map and compass course to get to practice that. So they have that skill set to fall back on but for most of them I think the biggest thing that it gives them is a sense of confidence. Even in this world of Alexa and GPS where if someone isn't telling them how to get to their destination they develop the confidence to realize they always have another skill set that they can fall back on.
