In the world of really cool tanks the Type 89 Ci Ro is at the top (along with the FT 17, Medium Mark A Whippet and M50/51 Super Shermans).
As I wait for the arrival of my platoon of Japanese ingenuity from Flames of War (I only ordered them a week before the release) I want to share this link for a review of the kit itself. I found it informative and will be useful once I receive the tanks.
For those not aware of this gem. It was used in China and along the Russian border in the 1930s. After Pearl Harbor, it was used in Malaysia and the Philippines.
