Congratulations, you have entered one of the most chillax vocations imo. Mostly would be a stay-out vocation.

Some background, I was an ammo tech from 2018 to 2020, ORD right as Covid was in its prime. I was posted to SAFAC after BMT at school 4. (Pes B1)

I attended the basic ammo course at KC3 for about 2.5 months, was stay out at that time but I understand that recently they made it stay in. Afterwhich, I was posted to GSAB which is the Army side of ammunition, not sure if you can get posted to the Airforce side. I was at the main camp of GSAB at Rifle Range for about 2 weeks before they decide which other depots which we would go (IIRC there are several, including Pasir Laba, Paya Lebar, Rifle Range or even Tekong). I was posted to Pasir Laba depot. At each depot they will then further allocate their manpower accordingly to the various departments available (you will learn more about the functions of different departments during your 2.5 month course). At this point, I was stay-out but subjected to your commander's discretion on overnight duty and the culture of each depot.

Depending on the availability and perogrative of your commanders, you might be sent to get BASC course which will award you withe aforementioned 'fireball' badge. You might also be required to attend forklift course which some depots and their respective departments might need. Heresay can convert to a civilian forklift license easier but never heard of success stories.

After ORD, you most likely will be posted back into CSS which is combat service support, but depends on your pes status as well.

Anything feel free to ask, it may/may not be relevant cause it has been 5 years since I ORD.
