I have that game and its a pretty nice solo strategy boardgame.
Most of the gameplay involves building and managing your squad. It's very well done.
Hornet Leader and Hornet Leader Carrier Air Ops are 2 different games though. Hornet leader is quite old while CaOps is kind of the updated version of the original HL with quite a few improvements.
There are other very interesting titles in the series: Phantom Leader being of them, set in the vietnam war era and Thunderbolt/Apache Leader, covering desert ops.
