It's gotten mixed reviews. It is very much focused on hardware issues, such a weapon performance and armor protection.
Some people point out it has soft factors, such as doctrine, but the doctrine rules are a joke.
Any vehicle can pretty much run around the board as the player sees fit. It does cover the hardware issues very well. The Persian Gulf War substantiated the results, at least against T-72s. It is so good on the hardware issues that I've seen it frequently converted to a set of miniatures rules. So it depends upon what you are looking for.
