As posted, individual tracks are like Fruils, AFV Club, Model Kasten, etc. where are the links are separate. Link & Length have normally four "runs" per side. The top run, the bottom run and the diagonal runs from the sprocket to the road wheel and the idler wheel to the road wheel.
In 1/72 scale, L&L tracks are preferable because of the size of the pieces. Vinyl tracks tend to put too much strain on the suspension too.
