The Rifleman Range is an Industrial Age Military Building. It is where a player can train the Rifleman, the ranged unit of the age. It is the first unlocked military building of the age. In order to construct the Rifleman Range, a player needs to have unlocked the Rifles technology. It is recommended to build the Rifleman Range, as the Rifleman is an effective unit that gains a range increase compared to the ranged unit of the previous age, the Musketeer. It also gains a lot of attack strength. The size of the building is also a "standard" 3x3, making it easy to clear room for it.
The Rifleman is most effective against heavy units, such as the Howitzer. It gains attack on rocks.
