Protection of armoured vehicles against chemical,biological and radiological contamination

The article presents problems related to mechanical protection of vehicles with different add-on armours against chemical,biological and radiological contamination.This applies to vehicles with additional passive,reactive and hybrid protection in the form of cassettes against piercing with anti-tank pro-jectiles,piercing with their kinetic energy of impact,and as a result of chemical energy of shaped charges as well as explosively formed projectiles.It has been shown how increased ballistic protection of these vehicles at the same time reduces their decontaminability in various places of the vehicle due to the increased additional surface of the vehicle with cassettes.Prevention of contamination of these cassettes has been presented as a way of reducing hard to reach surface for decontamination and a method of insulating construction elements(stands),fixing these cassettes to the vehicle,from the environment to prevent contact with contaminated liquids and dusts.The selection of appropriate materials is shown,which may affect the improvement of the decontamination efficiency of the vehicle with such cassettes.This applies to the use of materials with low absorption of chemical warfare agents,which prevent the accumulation of large amounts of these agents on contaminated surfaces and improve the effectiveness of decontamination.It also shows how to ensure better access of the disinfectant to as much of the vehicle surface as possible,covered with cassettes that have been contaminated.It shows how a vehicle,in particular with such cassettes,can provide protection against radar detection when Radar Absorbent Material is used on vehicle cassettes.     

From one exceptionalism to another: France’s strategic relations with the United States and the United Kingdom in the post-Cold War era

ABSTRACT

The failed expedition of Suez in 1956 and France’s subsequent strategic ‘divorce’ from the United Kingdom and the United States lies at the heart of a policy paradigm that has dictated France’s defence posture from de Gaulle’s presidency to the end of the Cold War. Some crucial features of the Gaullist posture remain today enduring references for French presidents in the definition of France’s exceptionalism. While it is so, there have been significant changes since the 1990s when it comes to France’s strategic relations with the United States and the United Kingdom. This article demonstrates the extent and mechanisms of this rapprochement by analysing it through three dimensions of policy change: modes of action, institutional commitments and discourses. The article demonstrates the dimensions’ mutually reinforcing effects and argues that France’s exceptional posture has de facto been reversed.
