So typically if you’re not already on contract, you’d contract as soon as you return from field training (beginning of AS 300 year). Normally non-contracted cadets would start the DoDMERB well in advance so they are green by the time that happens. I’m really not sure if you need to be DoDMERB cleared for field training. That would be something to take up with your cadre, but you do need to be cleared to contract once you get back.
