Engineer reconnaissance is the reconnaissance operations performed by combat engineers to enable forward movement of own troops, in war usually over territory previously occupied by the enemy. The activity includes provision of reconnaissance instructions on the intended route for which a commander needs an engineer reconnaissance report, identification of road and bridge symbols, posting of safe transit notices for identified bridge capacities, estimation for time and materials required to effect route repair, and performance of demolition reconnaissance to identify intended enemy demolitions.
