The idea is that one team would be given the Bergepanzer to use during the battle scenario. The tank would roll up next to a friendly destroyed tank, a sound card with a 50 second repair sound clip would play (including a blinking LED on the bergepanzer). Once the 50 seconds is up, the destroyed tank can return to battle at full strength. I will also install a Tamiya compatible battle unit in the bergepanzer so that it can take hits as well. It currently has a DBC, but I will be replacing it with the new SLU electronics package.
Here are some pics of the build:

The Plan



The battle unit connection is hidden in a crate on the deck.


My camera flash has washed out the colour, but I used some of my wifes old make-up to weather the tank. Then I gave it a spray coat of window frosting to seal it.
I am trying to figure out how to install the sound card to play when the user pushes the left stick up, but since I am changing electronics packages, I will probably hold off until my SLU arrives.
Although it does not have a working crane (that's beyond my current abilities to manufacture) it should add an interesting element to our battles.
I'll post an update once I get the sound card installed.
