CBRN route reconnaissance is normally assigned if the commander wants to use a specific route for what purpose?

CBRN route reconnaissance is typically assigned when the commander intends to ensure safe passage for friendly forces along a specific route. The primary goal is to assess potential threats or hazards, including chemical, biological, radiological, or nuclear (CBRN) contamination, and to confirm that the route is clear for safe movement. By conducting reconnaissance, the unit can gather critical data on the route's condition and any CBRN risks, which is essential for effective troop movement and operational planning.

Using a specific route enables a structured approach to transporting personnel and equipment, while also minimizing the risks associated with CBRN threats. Therefore, the emphasis on friendly movement aligns precisely with the objectives of CBRN route reconnaissance.
