The Barracks Tower employs and houses one Guard per level built (unlike a Guard Tower, which only holds one Guard). Guards live in the tower instead of citizen housing, freeing up beds.
| Tower Level | # of Guards |
|---|---|
| 1 | 1 |
| 2 | 2 |
| 3 | 3 |
| 4 | 4 |
| 5 | 5 |
| Tower Level | Max Patrol Distance |
|---|---|
| 1 | 80 blocks |
| 2 | 110 blocks |
| 3 | 140 blocks |
| 4 | 170 blocks |
| 5 | 200 blocks |
Note: Placing/upgrading near your colony border expands the border.
