The 7th game in The Gamer's popular OCS (Operational Combat System) series of games, this covers Operation Husky from the invasions to the fall of Messina.
The game includes a few shorter scenarios plus several different start-dates for the campaign games, based on the various critical events of the campaign.
Playing time can be a couple of hours for the shorter scenarios, but as with all the OCS games the real money is in the various campaigns, which - while quite manageable on the scale of these things - still can take from one to two full weekends to play to completion.
This is certainly the most rules-intensive of all the OCS games with air, ground, and naval units (including aircraft carriers!), airdrop capability on both sides, and the invasion and naval supply transport rules.
