Role of the 52d BEB CBRN R&S Platoon
After 70 years, the ever-present and reputable chemical, biological, radiological, and nuclear (CBRN) threat continues to mire U.S. forces throughout the Indo-Pacific Command. The 13th Korea Rotation Force (KRF-13), Camps Casey/Hovey, Republic of Korea, works to deter the proliferation and employment of CBRN munitions by adversaries. At the tactical level, a variety of CBRN units—most notably, the mounted CBRN Reconnaissance and Surveillance (R&S) Platoon, 52d Brigade Engineer Battalion (BEB), Fort Carson, Colorado—are responsible for assessing, mitigating, and protecting against CBRN hazards.
KRF-13 includes the 2d Stryker Brigade Combat Team, 4th Infantry Division, Fort Carson, which contains one organic CBRN platoon—the 52d BEB CBRN R&S Platoon. The CBRN R&S Platoon provides early warning detection against CBRN threats via route, area, and zone reconnaissance and surveillance. In other words, the R&S Platoon acts as the first line of defense through assessment, mitigation and prevention of CBRN threats.
The 52d BEB CBRN R&S Platoon is known for its M1135 Nuclear, Biological, and Chemical Reconnaissance Vehicles (NBCRVs) and associated hazard assessment skills. The platoon maintains the unique ability to provide early warning of CBRN agents by detecting and marking CBRN hazards through mounted surveys, surveillance, and sampling and preventing the spread of contamination. Moreover, the CBRN R&S Platoon is an essential enabler in protecting follow-on maneuver force missions.
M1135 NBCRV Maintenance
52d BEB CBRN R&S Platoon Soldiers occupy four key troop positions in each of three NBCRVs; the driver, vehicle commander, surveyor, and assistant surveyor all maintain vital roles and responsibilities during R&S Platoon missions. Each NBCRV position is complex and requires a vastly different skill set. To ensure success, the R&S Platoon began its training progression in Korea by implementing individual task completion related to each position in the NBCRV.
Mission-Essential Training
L6-qualified platoon members in a classroom setting with subsequent hands-on practice. In preparation for field exercises, Soldiers practiced collecting liquid and soil samples from the over pressured protection of the NBCRV. Sample tasks, and individual task proficiency contributes to the ability of the platoon to function as a team.
After weeks of individual training, the CBRN R&S Platoon conducted a series of collective training exercises on Camp Casey and at Rodriguez Live-Fire Complex, Pocheon, Republic of Korea. These platoon-focused training events improved coordination among NBCRV crew positions. As the surveyors gained proficiency in collecting samples, other platoon members learned to perform tedious sample packaging procedures. Depending on the nature of the hazard (biological or chemical), they practiced packaging air, liquid, soil, and vegetation samples. In addition to collecting and packaging samples, platoon members marked contamination and the assistant surveyor completed documentation to enable sample transfer.
Following individual and collective training, the CBRN R&S Platoon trained on more complex scenarios, such as those involving collective reconnaissance missions. Along with practicing Battle Drill 1 (React to Contact), the platoon reviewed tactical combat casualty care drills and recovery operation steps to prepare for challenging missions. Moreover, the Soldiers practiced recovery operations in Mission-Orientated Protective Posture (MOPP) 4 personal protective equipment to simulate a realistic mission scenario. (In the case of an intravehicular casualty, crew members must be able to assess the casualty; assume the appropriate MOPP level, if necessary; and in some cases, transport the casualty to the nearest casualty collection point.)
Combined Training Exercise
Training with external units is important in maintaining interoperability with adjacent CBRN units, including ROKA chemical units. Such training increases the capability of units across the Korean peninsula and enables higher headquarters to be prepared to fight and win in CBRN-contested environments. Although, due to Army structure, the future of the 52d BEB remains uncertain, the CBRN R&S Platoon will continue to be a vital brigade reconnaissance asset, protecting maneuver forces at the forward line of troops.
Cultural Immersion
The CBRN R&S Platoon conducted several cultural-immersion trips to increase understanding and enhance team building, both internally and with its partner force. The first outing included a trip to the Korean War Memorial, Yongsan-dong, Yongsan-gu, Seoul, South Korea, which offered an opportunity to remember the Soldiers who fought in the Korean War. The event also enabled Soldiers to learn about various weapons systems and equipment previously used by the North Korean People’s Army, which provided insight into what a future fight could entail.
The role of the 52d BEB CBRN R&S Platoon in M1135 NBCRV maintenance, training progression, and cultural immersion set the standard for future rotational CBRN R&S platoons on the Korean peninsula. The successful performance of the platoon provides assurance that the Korea Rotational Force is ready for the fight tonight and instills hope for units to come. In the meantime, the CBRN R&S Platoon will fight for excellence in its next adventure.
