The game is very fun and plays similarly to confrontation. The big difference with at-43 and confrontation is the activations switching from player to player unit by unit.
At the start of a round both players make an Authority test by rolling a d6 (and adding their commanders leadership value to this roll) The winner of the roll gets to activate his first unit first. After the winner makes his moves with his 1 unit, the activation switches to player two. This continues till all units have been activated.
This is just one of the unique factors of this game.
I will add more to this post when I get some more time.
