ITI = Infantry Training Institute. I was in almost always in ITI during my ICT days.
People who posted there were mostly from the Infantry Regiments. (I was from 5SIR last time). U will most prob be doing this u did during your active days, unless they decide to send u go do conversion course to another vocation.
Since u was an auto tech, my guess is that u will probably join the MT line bah. But ITI vehicles seems mostly managed by outsourced company (Comfort delgro IIRC). So not sure if there are still NSF or NSmen auto tech in the camp
Bring enough coins to buy drinks from the vending machines conveniently located around the camp. The Cobra Mess is quite a distance from the Bunks.
FBO means bring all your barang barang to camp lo. My time in ITI is stayed in, Nights off are given at the discretion of your CO, OC or PC
