Setup: Ammunition is a mission in Grand Theft Auto Online as part of the Agents of Sabotage update. It is part of the Oscar Guzman Flies Again mission strand.
Description[]
After completing all of the previous preparation missions, Oscar Guzman will set up the previously stolen DH-7 Iron Mule(s) at the Port of Los Santos, closer to an Eberhard cargo ship carrying the Titan 250 D ammunition they need.
Oscar will fly the player to the Port of Los Santos in his Velum 5-Seater. The player must land at the port and get in the DH-7 Iron Mule. Additional Weaponized Conadas and Weaponized Dinghies can be used by the player or their associates to escort them.
The player piloting the DH-7 Iron Mule must use the vehicle's hook to steal the cargo containing the Titan 250 D ammunition from the Eberhard cargo ship, which will be guarded by personnel on foot which respawn infinitely, and four Anti-Aircraft Trailers with dual MGs, which can severely damage the DH-7 Iron Mule and should be taken out as soon as possible, as they will not respawn after being destroyed.
Explosive crates are available at the docks, at the airport and close to the barges surrounding the cargo ship. They can be lifted up using the DH-7 Iron Mule and then dropped onto Eberhard's security to deal damage or destroy the anti-aircraft trailers.

Communication jammers and chaff countermeasures will be provided to the player. The former is used to block Eberhard from calling for backup for about 4 minutes and 47 seconds. After that, two (three in hard mode) enemy Weaponized Conadas will spawn, and four more can be called after the ones present are destroyed, appearing every minute. They will fire unguided missiles and machine gun shots at the player as long as they are in range of the cargo ship. The player will also be required to stay low while lifting cargo, as the cargo ship will fire a remote control missile at them if they go above the altitude limit for too long. The chaff countermeasures provided can briefly prevent the missiles from being fired, but they only have five uses.
Additionally, the player can board the cargo ship using the provided helicopters or climb up the ship's anchor chain, and then disable the remote missiles at the terminal.
Heavy armor

Weapon crate

Mogul upgrades

The Titan 250 D ammunition must be delivered to Oscar's contacts at the Maze Bank Arena parking lot to be stored for The Titan Job. Optionally, additional equipment can be stolen from the cargo ship, each of them providing a different benefit for The Titan Job. Once collected, they become available for all future runs for The Titan Job.
- The heavy armor doubles the amount of HP the player has.
- The weapon crate gives a Combat MG Mk II with armor piercing rounds, an SMG Mk II, a Military Rifle, a Pump Shotgun Mk II with explosive slugs, and Pipe Bombs for the player in addition to the fixed loadout they will use for the job.
- The mogul upgrades provide dual MGs, dual turret guns, cluster bombs and improved handling upgrades for the Mogul.
Trivia[]
- The DH-7 Iron Mule's engine will occasionally cut out after receiving some damage, but it will never shut off until it is destroyed for good.
