There are two smaller pillboxes referred to as Fire Posts and these support the main pillbox, and enable the defensive team to spread out over the site but still remain secure in a defensive position. These two fire posts are essentially identical in size and shape but one is ‘right handed’ and the other is ‘left handed.’ Their walls are one foot thickness (30 centimetres) and constructed of two leaves of brick with a solid concrete core, at best this would only have been bulletproof. The four loopholes are made from precast sections comprising the top and bottom halves leaving a long horizontal slot for observation and defensive fire purposes.
Each entrance is protected by an anti ricochet wall and the guards would have to duck under the low door lintel to enter.

This telephone box is located to the North side of Fire Post number 1. It shows they must have had good communications between the boxes.
