Nowadays, on the battlefield, a clear sight of the target is paramount for a successful engagement. Laser guided rockets and modern sensors that offer new means of targeting and observation have changed modern battle tactics. The equipment evolution has brought optical systems at a new progress peak, which made possible day or night observation in unfavourable conditions. On the reverse side of the observation systems, namely the target (friendly forces) is another factor to be accounted: troops masking. For this aim, new devices, such as pyrotechnic obscurants systems, have been developed to counter modern observation systems, which are in a continuous evolution. Therefore, the first step in optoelectronics systems countering is to study and analyse the way they operate in different regions of the electromagnetic spectrum. In this context, the aim of this paper has been to perform a detailed analysis of the thermal systems regarding their observation capabilities in clear atmosphere and in the presence of infrared obscurants. Using both theoretical and experimental analysis, it has been shown that it is difficult to counter thermal observation systems by pyrotechnic smoke obscurants..
