I like this idea, and when the player carries an FOB it should run almost twice as fast, maybe even be able to automatically step over one block inclines?

Forward Operating Base.

Double the size of the current base, maybe even make it big enough to walk into. And give us the ability to carry smaller bases closer to the battle. Give them a limited number of new clips and HP they can supply. Also make it so that you can't sit in them and heal when you take damage. Limit the number of FOBs the base can give to like, 3. When an FOB runs out of ammo and health, it disappears.

You take an FOB from the main base, maybe making yourself unable to use weapons. Then you take like...5 or 10 seconds to set it down somewhere else on flat ground. Make it the size of the current base.

Right now, it's just a pain to go back and get more ammo or health if you run low and it's just way faster to get killed and respawn.
