How does the GDF Medics Supply Drop work?
Key 6 (_weapon05) will select the Smoke Canister. Throw the canister on the ground, somewhere outside, and a plane will drop a Supply Crate down to you. Stand next to the Supply Crate and it will replenish your health and ammo. Each Supply Crate can only give out a limited number of Med and Ammo Packs. Supply Crates can be destroyed by fire, so protect them. One good place to drop them is right in the spawn area so that players can top off before heading into the fight or on a reverse slope near the Objective.
