To answer the OP (even though he surely knows now): Yes, they do.
I´m still very unhappy with the expansion. Okay, the models look great. But I have bought to boxes, and in each of those (even with the added sponges), ALL of the british tanks had one or more broken guns that ran wild in the box and were hard to be found and reattach...
Great game, but bad packaging, as I´m very sorry to be feeling to have to say.
