It's what happens when golf carts go to war.
From the release:
One of the most important designs in the history of tank development, the Carden Loyd tankette inspired a huge number of similar vehicles worldwide, including the Panzer I and Russian T-27. Now you can add several variants of the carrier along with a 2cm Oerlikon gun and crew to your army.
The Carden Loyd tankettes were a series of British pre-World War II tankettes, the most successful of which was the Mark VI, the only version built in significant numbers. It became a classic tankette design worldwide, was license-built by several countries and became the basis of several designs produced in several different countries.
