| Notes | The Ark Mk. II came in two types the U.K. Pattern and Italian Pattern, both were different and could gap different sized obstacles due to the different sized ramps. The plan was for when the tank had drove into the gap then vehicles just simply drove directly over either ramps or in the case of the Italian Pattern over the top of the tracks. |
