The beginning of the Cold War as well as the recognition of nuclear weapons as new and decisive combat measures opened a new stage in the history of Polish chemical corps. In the face of another world war, this time with using weapon of mass destruction on both sides, chemical forces were not only restored but also intensely expanded and trained. The emergence of divisions’ and military districts’ chemical companies in the 1950s and independent battalions in the next decade resulted in several times increase in the number of manpower of these specialized troops, larger organizational structures and the adaption of the concept for their usage in the changing requirements of the battlefield. As a result, at the turn of 1960s and 1970s chemical forces achieved the biggest combat capabilities in their history, as they had four trained and fully manned chemical regiments at disposal, that after further mobilization development to Chemical Brigades supported the levels of two Armies and the Front. The main purpose of this article is to present secret until recently organizational structures of Chemical Brigades of the Army and the Front, their combat capabilities and the concept of operation. The article includes mainly collections of Archives of the Ministry of National Defense and sparsely occurring works and articles, which, moreover, present the issue of Polish chemicals troops only in an outline or a fragmented way.

Soldiers can wear chemical, biological, radiological and nuclear (CBRN) protective clothing to be protected agaist warfare agents. The disadvantage of that clothing is that higher protection introduces higher physiological burden. Therefore an optimum between comfort and protection must be found. Models of all relevant processes were created to find this optimum. The airflow profile around a cylinder with clothing—representing a dressed human body part—was modelled. This flow profile was used for calculating the agent vapour breakthrough through the clothing and for calculating the deposition of agents onto the skin (as indicators for protection). The flow profile was also used for calculating the temperature profile around the body part and the relative humidity underneath and in the clothing (as representative for physiological burden). As a result a tool was created, which can be used to identify the optimum properties of CBRN protective clothing, depending on the intended mission of the soldiers.

The article presents problems concerning the organisation and realisation of NBC defence endeavours in the USA ground troops on tactical and operational levels. In the introduction the author recollected the definition and endeavours of NBC defence and these endeavours management bodies (people in charge) on selective command levels. Further the NBC assets have been reviewed. A special attention has been drawn to the organisation of NBC defence units and subunits, data analysis centre and tasks performed by them. Also the basic equipment, necessary to perform these tasks has been characterised. The NBC defence preparation by commanders and people in charge of appropriate command levels and combat documents prepared by them have been discussed. The final issue touched on in the article is the realisation of NBC defence endeavours. There have been defined the warning and report system (NBC WRS) functioning and organisation, contamination recognition including contamination detection and monitoring and recognition of NBC weapons contamination areas and also the ways and principles of contamination elimination.
