Here's a new 'Proving Grounds' trailer which showcases the just released Private Military Company expansion pack to Bohemia Interactive's Arma 2: Operation Arrowhead.

Marek Spanel, Bohemia's CEO comments "This new terrain demonstrates the genuine diversity offered by Arma 2's environments, including detailed features like deep ditches and craters. It may not be as vast as our other, massive maps, but it has been crafted with care and precision - and offers a distinctive set of new gameplay possibilities."
