By striking wallet-scouring operational wargame Command Ops: Battles From The Bulge repeatedly with sledgehammers, Matrix Games have managed to chip off a small scenario-sized piece. Eight tutorial vids make up the lion's share of the 525MB fragment. If you're new to the unique Airborne Assault/Command Ops approach, you'll definitely want to watch these before attempting to dislodge the regiment of doughty Volksgrenadiers defending St Vith.
Prior to posting yourself to the frozen Ardennes, you may also want to make sure you've got at least three hours of clear game time available. In a frankly bonkers move, we're expected to orchestrate a five day op with no access to a save button.
Thankfully the scenario is well-chosen and roomy. Once you've grabbed the one useable bridge in the south of the map, there's plenty of space to manoeuvre and ample opportunity to experiment with the game's matchless delegation system. Try different approaches over the course of several sessions and you should witness Panther's impressively flexible AI being impressively flexible.
