"When equipped the Drop Station pack gives 25 energy and 50% more ammo. You may also deploy a light inventory station that can re-equip your current armor or simply refresh your ammo. Armor will not be changed."
The Drop Station is an unlocked pack/deployable for the Medium Armor. While wearing the pack, it increases the player's energy pool by 25, and provides 50% more ammo to their weapons. Once the Drop Station is deployed, it acts as an inventory station, but will only resupply the player.
