Love the pic you chose.  Well done. 
  
Yep, everyone's right.  The AF will teach you what you need to know.  I will say, however, that basic abilities go a long way.  I flew the mighty tweet (it had very old school instruments)....and I learned a lot.  The C-17 is glass (as most airframes  are nowadays) but I feel comfortable flying old school, too (it does have standby steam gauges).  I've noticed over the years the T-6 types rely on the automation/glass and don't understand the steam.   
  
IMHO, if you're trying to be a good instrument pilot (good on you), I'd go fly some approaches in a 172 under the foggles.   I mean this sincerely.  Yeah, the panel won't apply directly to a T-6 or a C-17 or whatever, but the basic skills definitely do. 
  
Edit: do approaches in a 172 that has steam gauges. Almost forgot that some current 172 panels make what you'll see in the AF look archaic.
