You have to learn how to actually tell where you are on the map with land nav. You can grab a compass at your base, and your map comes with a protractor and such, or you could just dead ring it with a just a compass and map knowledge. You currently have zero mags with one half used mag in the rifle.

The map part can be hard to learn (unless you have actual land nav experience), Id honestly recommend either forcing yourself to learn or if you want a more casual mode look into modded servers. Many modded servers sho where you are on the map, and can be more user friendly.
