Unlike traditional real-time strategy games, collecting resources or building specific structures is unnecessary for creating an army - the same principle that was introduced by Nether Earth, one of the RTS games ancestors. Regions and structures within their borders that actually manufacture the units are captured by moving troops to their respective flags. All you need to do is to hold acquired position for a certain amount of time while the unit is manufacturing. (wikipedia.org).
