The siege against humanity

You and your team figure that the second squadron needed ammo more because they were in the open, the driver slams her foot on the gas and next thing you know your flying down the trails, whipping left and right, the buggy jumps out of the bush and into a large open plain, you see a group of soldiers running towards a tower in the middle of the field, but bullets are flying out of the forest on the other side of the field. Your team decides that there are two ways to handle the situation, get to the tower and drop the ammo off, leaving back to base to get more ammo and return to the other squadron, or you can drop the ammo off at the squadrons position then go and give them cover fire from the base of the tower.
