Alas, they chose not to include the dance number on the trailer. Still, it looks OK for what it is. They got the fact that Pakistani armur was limited to Chafees in Bangladesh right. Not so sure about using the PT-76's main gun for AA fire. Might have to have a look for the full movie.
I've always wanted to do the Indo-Pakistani wars. You can proxy the forces but I'd love to see someone come out witha dedicated range in 28mm. Unlikley though.
