Iron Curtain differs from Trophy in that instead of firing outwards to intercept projectiles, it firesdownwards from the top of the vehicle it's protecting straight towards the ground.

Iron Curtain can deal with multiple incoming projectiles at the same time, and the downward blast helps to keep anyone around the vehicle from getting hit:
