Besides the airborne they come with? How much do you need to keep up?
Look I play plenty of ez mode verion 1, I know how eazy it is to kick hell out of lame ass Riflemen and use USF's pathetic tech tree against them. With USF you've got easily the worst starting game of any faction, nothing to work with. Riflemen? A mortar? LOL. The funny thing is as bad as Riflmen are and as easy as they are to counter, Pathfinders are even worse. But of course they cost 290 MP for unknown reasons.
