How Do Military Shelters and CBRN Protection Safeguard Forces from Emerging Threats?

Military shelters can be traditional static shelters built for maximum protection against kinetic, electronic and CBRN threats or mobile shelters with lighter level of protection. Both types of shelters benefit from CBRN detection and protection as disrupting the operational capability of military shelters causes direct damage to friendly forces operations. This blog text concentrates on both static and mobile command shelters as they are generally one of the highest value targets in large scale military operations.

A command shelter can be a permanent structure built above or below ground or a mobile solution such as field deployable container or trailer. Mobility is essential for mobile shelter solutions as they need to be deployed and redeployed fast.

The command shelters protect the systems and personnel from kinetic threats as a minimum and additionally from CBRN and EMC threats and provide a comfortable working space for the personnel.

Underground permanent structures offer arguably the highest level of protection from all threat types as they can be built deep underground and managing their RF and IR emissions is easy and they are mostly hidden by design. Above ground structures offer high level of kinetic protection as well but unless they are made to look like regular buildings they stand out to anyone looking for special kind of installations. Using traditional intelligence methods are used to discover the locations of these types of shelters making them easier targets for adversary operations.

The idea behind mobile command shelters is that they can be setup and commissioned rapidly in the operating area providing tools to keep the military operations command chain effective and allowing for near real-time collection and distribution of relevant battlefield information. Mobile shelters contain all systems necessary for operations and can typically be functional within minutes of being deployed. Once deployed they are typically camouflaged to match the environment better and make them less visible to enemy reconnaissance.

Container based mobile solutions can be 1 TEU or 2 TEU containers. These sizes make the most sense as they are standard sizes and all container management systems can easily handle them. Different kinds of field deployable feet and mobility platforms are also available for standard size containers for fast deployment.

Trailer based mobile solutions are constructed on a trailer deployed by a truck. The trailers are typically expandable giving more working space to personnel.

The most common CBRN threat for command shelters is the chemical threat. Chemicals can easily be deployed in the area where the command shelters are located and cause an almost immediate effect on personnel.

Biological and radiation threats take longer to influence but might be more potentially used against personnel in permanent shelters. Localized deployment using special operators targeting the permanent shelters air intakes would be the most effective method of spreading chemical, biological or radiation substances.

These threats can incapacitate forces, disrupt operations, and cause long-term health consequences. Therefore, CBRN protection is not optional—it’s mission-critical.

Integrating CBRN defence into military shelters involves several layers:

• Sealed Structures
  • Advanced sealing technologies prevent leaks, ensuring contaminants cannot enter through gaps or seams.
• Monitoring and Detection
  • Sensors continuously track air quality ensuring that air inside the shelter is breathable.
  • Chemical, biological and radiation detection ensuring rapid deployment of CBRN filters in air systems.
• Air Filtration and Overpressure Systems
  • Shelters are equipped with CBRN filtration units that remove contaminants from incoming air. Overpressure ensures that air flows outward, preventing infiltration of harmful agents through gaps, cracks, or leaking seals. Overpressure system is especially important for mobile shelters as they are more suspect to leaks after multiple deployments.
• Decontamination Zones
  • Many permanent shelters include airlocks and decontamination chambers, allowing personnel to remove contaminated gear before entering the safe zone. Mobile shelters do not normally have these facilities.
• Hybrid energy systems
  • Shelter can be equipped with backup power system consisting of batteries and power generators for the situation when grid power is not available. Battery system also enables fast commissioning of mobile shelter systems when the local temporary grid is not yet available.

Military shelters equipped with CBRN protection systems are more than just physical structures enabling C2 to be conducted in comfortable environment—they are lifelines in potentially hostile environment allowing command and control to function in a less stressful environment.

As threats evolve, so must our protective technologies including CBRN detection and protection, ensuring that armed forces remain safe, operational, and ready for any challenge at all times.
