Immobilised tank markers (update)

While writing and testing some simple WW2 rules inspired by Featherstone, Grant, and other sources over the past few weeks (see recent posts). I have decided to include immobilised tanks in the rules. To indicate a tank is in an immobilised state, I opted for a visual marker using a thrown track as a suitable representation. 

The tank in the foreground is immobilised - marked by a thrown tank.

I found the easiest and fastest way to create a thrown track marker was using felt and add some drawn lines with a permanent marker. I might look at some other materials for this purpose in the future.

The plain cut felt on the left and marked up on the right with a permanent marker.

UPDATE

I have tried some brown corduroy material which seems to work better for the tracks.

Brown corduroy material seems to work better.

I will probably dry brush some sand colour paint onto the corduroy.
