Signals Platoon Operational Deployment
The Battalion had generally three distinct operational roles. Often required to advance towards the enemy to probe out his defensive position and locate his 'strong-points', this was known as advance to contact. In principle, the leading rifle company would have one platoon forward as it advanced towards the enemy, seeking to overcome whatever resistance it met until it could no longer do so. When the platoon was fully deployed and pinned down, the company commander would determine from his own observations and reports from the leading platoon commander about the enemy's positions and strength and then attack with his two remaining platoons. If the opposition was overcome, the advance would continue until the leading company was no longer able to move forward but pinned down by the effectiveness of the enemy's defences.
The Battalion Commander would then consider his options for deploying one or more of his rifle companies in reserve, determined to probe as fully as possible the extent of the enemy's defensive layout. Depending on the order the Brigade Commander had received from the Division, he would be ready to deploy the two battalions under his command.
