Sniper is akin to Western series like Strike Back but in this case its a stand alone film.
China produces a lot of these kinds of films and series. As you might expect, they do have something of a pro China military message but then they are made first and foremost, I believe, for the Chinese domestic market.
This one is fast paced, driven predominantly by exposition and very watchable, if, that is, you enjoy military action flicks. Acting is decent too, lending a little more depth and believe-ability to characterisations.
I found this one free, like so many others from China, on Youtube presented by legitimate Chinese entertainment company's. Subs are available and they are competently done, for the most part.
