Well I just picked up Tomorrow's War and Operation Uruzgan from Ambush Alley.
A quick skim of Tomorrow's War and there's a lot of material in there.
Operation Uruzgan also looks excellent. Now if only Flashpoint or Eureka would ever get around to producing their modern Australian Infantry in 15mm!
Luckily for the time being; the book has a guide to converting to British and US troops.
