I picked up at Warfare a new set of rules called Black Ops, published by Osprey.
They have been described as a quicker version of Force on Force, so, small forces, regular troops vs insurgents, time to sit down and have a good read of them.
Quick description of the rules
Black Ops is a skirmish wargame of tactical espionage combat for two or more players. It recreates on the tabletop the tension and excitement of modern action-thrillers such as the Bond and Bourne films, The Unit or Burn Notice TV shows, and the Splinter Cell and Modern Warfare series of video games. The fast-play rules use regular 6-sided dice and a card-driven activation system to keep all players in the thick of the action, while the mission generator provides a wide range of options for scenarios, from stealthy extraction or surveillance missions to more overt raids or assassinations.
