Actually nothing could be further from the truth. From experience within the IT world of the Military from pre network days with standalone Z-100 dual floppy to full blown modern data centers. Innovation on the part of the IT workers is continuously encouraged and greatly rewarded. In my experience, IT professionals at least in the Air Force that are not passionate about keeping up with technology and finding better ways to do things and learn as many different aspects of IT are not in the IT world for long.
There are really 3 types of IT people in the military.
Those who get as many certs as possible so they can fill their resume and get out
Those who are passionate about what they do and what they can learn
Those on their way out of the field or the military.
If someone has IT experience in the military from early in their career then they ended up with a less technical job or if they were in the military for a short time after getting into the IT field without collecting certs or an IT degree, then maybe you are right. But someone like me who spent 22 years from token ring, Banyon Vines and AUI transceivers to the latest modern data centers had to continuously improve or find work elsewhere.
