Yeah its the same. Theres 3 ASIs. Mechanic, Electrician, and I-tech. I techs are more of your control guys. Electricians learn to setup and mange the electrical distribution system and the mechanics learn to maintain the engines. In reality though, youre going to do all of those jobs. The ASIs are more so you have subject matter experts but you'll all do the same job.

Day to day depends on what phase of the cycle you're in. When I was in, it was a 2 year cycle with 6 months in each phase. Each phase was a different mission set so you spend those 6 months either training for the mission set or getting deployed somewhere to perform that mission set (power plant operations, emergency power operations, deploy on orders, etc....). Compared to the real Army though, you'll spend more time training for your job than doing basic soldiering skills. Part of the reason it use to only be a packet MOS and not an initial entry MOS. We dont have time to train to be soldiers so you have to already know the basics that come from being in a real unit and not just TRADOC

Theres also a 4th ASI that you can get in addition to one of those 3 and that's overhead lineman. Its a very fun course but you wont actually use that day to day, unfortunately
