Army readiness shows signs of improvement, but gains could be fleeting

This article lacks specificity.

This is not something that has a quick fix. You have to keep after it. We constantly access new untrained people and they have to be trained and refresher trained or the system breaks down.

This article doesn't tell you the things that were being rated - so, hard to figure. But it did mention a shift in training. So, question: Is there, or has there been, a substantial problem with atrophied war-fighting skills as a result of the emphasis on "counter-insurgency" and the like over the past 15-17 years? (I remember in the late 90s, that there was already a big emphasis developing on MOOTW (which at the time seemed to be mostly about what was called "peacekeeping", so one might say that such an emphasis went back even pre-9/11.) I've read about the SFABs which seem to separate that stuff out to the side.
