1st season setup the premise and plot
2nd, 3rd, and 4th season is action-packed
story, guns, violence, terrorists, special forces, female soldiers,

beware in season 2 to 4, there are sex scenes, best to watch with headphones and behind closed doors

I didn't think season 4 is out yet... It's the final season too
