A few points here, and no, it's not terrible. I think it just needs quite a bit more thought and more than a little polish.
First, this guy isn't acting much like a sniper, heading in anyway to support much of anyone. Snipers are designated to provide cover fire from a distance. They do everything they can NOT to take part in direct field combat. That's why they tend to nest on tops of buildings and to some side or flank away from the direct enemy fire. This guy is either a plain foot-soldier (popularly known as infantry) or as a sniper, he's been found and is being forced to a new location.
Second, this comes across as an attempted commercial for '3u media'. As such, while great to invoke images of warriors and defense. It would only best apply to a company that defends or secures something as part of their services. Or... you kind of need some other battle that they are offering to fight in your stead (as a customer). From there, all you really need is the visual analogy to follow through and 'sell the idea'. A media company might be fighting the 'good fight' against... say 'media giants' and you can have your enemy hordes pose as whatever images might evoke the media giants that your customers find themselves up against. Service reps could be the men in black suits... companies could be represented in masses of robots or the broadcast tower in the distance that this guy is clearly heading to destroy. And yes. before you ask, you can try any of those.
Finally, I know this may well be a 'fake commercial' or just a school project. I get it. Truly some quality thought and planning in what you want to say and how to go about it will go further distances with instructors and help you learn this advert' stuff better for your own future than just slapping something together to say 'I did it' and hope for a grade. Right? That's why I try to offer something constructive. It does no one any good for me to just shoot an idea down unless of course... it really can't be saved. You have a lot of potential here, and some good idea about how to approach a sales worthy message. It's just not quite ripe yet, if you want my honest opinion.

thats one hell of a commercial!
