RE: 1/16 figures
I use the 1:18 scale Ultimate Soldiers and I think that they add a great deal to the tanks. [sm=thumbup.gif] The detail is much better than I could possibly paint, too. Plus, since they are "posable", you have more freedom and a variety of positions.
They are about $5.00 each at Wal-Mart or you can find them on-line, even on Ebay.
