To outsiders, Rosetta may appear to be a research-oriented organization, but in fact, there are experts from a wide range of industries within its ranks. For example, Rosetta has pursued a highly successful partnership with a certain country's military to design a series of advanced high-precision drones.
Before long, this partnership bore fruit, and Rosetta was able to develop a series of portable battlefield drones which can be carried into battle by the soldier in the form of a backpack. A lighter flying component can be removed from the backpack and released into the air in a matter of seconds, giving the soldier an extra edge in combat.
