In Ubisoft’s official blog, Editor and “Communications Mercenary” Mikel Reparaz describes the game, saying:

The first mobile game in the Tom Clancy line, this title focuses on the player – a sniper – who doubles as the commander of his own armed militants. This coincides with the ability to take out enemies on your own, providing the absolute best of both worlds of war. Players will have to wait and see whether this will be a boon or a distraction in the middle of the game’s fast-paced play. 

ShadowBreak’s Creative Director AJ Morales elaborates a little further on what sniping brings to the game and its players:

The full game is currently available in Canada for both iOS and Android, but will be available worldwide at a later date.
