The Pillbox is a defense which is extremely powerful against Infantry. It is also effective against lightly armored vehicles, yet weak against heavily armored vehicles such as medium tanks or heavy tank.

The Pillbox is an Allied counterpart of the Flame Tower, it is significantly deadlier in terms of fire rate and range. However, the flame thrower deals more damage per hit.

The Pillbox has to be manned by a single infantry unit. When constructed, a single rifle infantry will be inside. A rifle infantry in a pillbox uses the Vulcan weapon which is significantly more powerful than the rifle infantry's own weapon. Other units use their regular weapon while inside a pillbox. The rifle man that comes with the pillbox can be replaced with Tanya for enhanced effectiveness.

The pillbox will stay functional even in low power mode.

The camo pillbox is a cloaked variation of the pillbox.
