Quick recommendation: Look at the article "Training observations" on Volume 2 Issue 1 of the Journal of Military Operations.
It's about observations after a two-week battle group* exercise (apparently Brits). It gives a nice glimpse of how difficult it is to shake off "Afghan-ism"s.
(I also like the author's humour.)
* Battle group in UK = typically a reinforced, possibly mixed, battalion as far as I know..
