I haven’t found any information about what training is required for a Cargo Mate (Chief Mate) on an MSC ship carrying ammunition.
Is it just the Ammo Supply Administration Navy class (CIN#: A-041-0040) or are there additional training courses and requirements?
Seams like you should at least be required to attend the AMMO-74 Explosives Safety Officer Orientation Course/CERT (CIN#: A-4E-3009) as you are acting as the Explosive Safety Officer while the ammunition is aboard your ship. However, MSC taking shortcuts in training wouldn’t surprise me at all.
Not required by MSC, but strongly suggested, is MSC’s own Ammo Management class. Good idea to also have taken the Magazine Sprinkler class, so you know how not to accidentally activate them while testing quarterly. Don’t expect to be sent to an ammo ship as cargo mate, at all. They’re too short of 1/O’s, so you would be C/M. 2/O’s and JSO’s are doing all the cargo on them now. Talking CIVMARS, CONMARS may have better manning.
The T AKE ammo ships are also considered tank vessels. So Tanker PIC would be needed. Running the flight deck during vertical replenishment would need HSO or LSE. The Cargo Mate would be overseeing Bosun Mates on the UNREP rigs so there may be a class for that too. Cargo Mates run the reaction force onboard so they are in charge of that force and the weapon handling and stowage. Small arms instructor would be beneficial, not required. Other contributors can probably add to this list. Do not become a MSC cargo mate if you want to maintain a life on shore.
You’ll do STREAM as part of new employee training along with basic Ordnance Handling Awareness. HCO is a must, if you can get in the class, along with Gas Free Engineer. That’s even harder to get into. Both HCO and GFE are required no mater what kind of ship you’ll get assigned to.
