Hello.I'm from 2 Field. To join up all you need is the normal requriments for NCM. We require a bit higher on intelligence scores though, becuase we do charge calcualtions for explosives.
We do our QL3 (basic engineer training) in Gagetown. It's probably the hardest entry level course in the Canadian reserves. It's worth it though.
If you have any questions on 2FER or engineers in general, feel free to email me.
