I am new to the forum, but I saw this post and wanted to give my feedback.
As someone who had very little base knowledge, I thought the Power Pack was really useful.
Maj. Rush gives a great overview of all the branches and the physical requirements, and the different routes people take to fly in the military.
Overall, it was a great source of information as far as getting it in one place. When I was searching the internet, I found that I was finding differing information, which turned out to be flat out wrong. I was really happy with the Power Pack, and would recommend it to others.
