Yuri and Asada are on a mission to retrieve confidential data discs that were stolen from the government, but once they finally track down the items, AI-controlled tanks threaten their lives. It’s up to Leona Ozaki’s Tank SWAT team to take action! But even if the enemy tanks are destroyed, danger still exists in the form of a mysterious android that has taken Asada hostage and fitted her with a bomb collar. Leona must make a choice: does she risk losing the data discs and the lives of the rest of her team for the life of a single team mate?
After the third world war, the organization known as the General Management Control Office constructed the city of Olympus – the only place where chaos and anarchy doesn’t hold sway. It seems unthinkable that terrorists are out to disrupt this pristine society, but the threat becomes very real to SWAT officers Deunan and Briareos when their squad mates are killed during a hostage situation. Bent on catching the lone escaped terrorist, they soon find themselves involved in a plot to undermine the whole existence of their Olympus.
Appleseed and Tank SWAT, besides having Masamune Shirow at the helm, are both short, action-packed OVAs about a police mission gone wrong. Each has unusual characters (cyborgs and catgirls, oh my!) and a futuristic, somewhat cyberpunk feel. I didn't care much for either of these, but fans of one might enjoy the other.
It is the year 2023, 30 years since the time of the Silent Crisis that brought the world to the brink of destruction. In the present, other-dimensional beings known as the Lucifer Hawk are running rampant, and threaten to take over the human world. The only hope for mankind is the AMP -- the Attacked Mystification Police -- a group of women with paranormal abilities who are dedicated to stopping the Hawk at all costs. With the frequency of attacks increasing and the bodies piling up, it's up to Katsumi Liqeuer and the rest of the gang to stop the invading threat... before it's too late.
If you are looking for something better than Tank SWAT and liked the police aspect, you might enjoy Silent Mobius. It has more of a mysterious feel, monsters aplenty, and has plenty of character development and action. Remove the campy nature of Tank SWAT and add everything better, and you have Silent Mobius.
