Description: The article outlines the general provisions of the improved methodology for assessing the survivability of the radio troops' grouping while participating in the repulsion of an air strike. The methodology is analytical and describes the dependence of the losses of the group of radio troops on the main factors affecting them. The presented methodology is based on the methods of analytical-stochastic modeling of the military actions of the group of radio troops, as well as, in contrast to the existing, theories of games for predicting the risk of loss of combat capability by the radio engineering unit in the choice of position in the face of the threat of its fire damage. An indicator of survivability was the mathematical expectation of the number of radio units that retained their combat capability or restored it until the end of the air strike. The indicator is sensitive to changes in methods of using the means of air attack of the enemy, methods of interaction with fighter aviation, anti-aircraft missile troops, forces and means of electronic warfare, changes in interfering conditions, technical state of radar weapons, as well as maneuverable methods of military applications of radio units. The criterion for evaluating survivability is the mathematical expectation of the required number of stored radio engineering units of the group according to a variant of combat application, in which the radar coverage of radar information users with the required level of efficiency is carried out. With the help of the method, it is possible to assess the success of the participation of the radio troops in reflexion of the air strike and to predict the degree of readiness for further tasks, taking into account probable losses. The methodology can be used in the interests of substantiating the appropriate methods of using the group of radio troops and developing practical guidelines for ensuring survivability. The application of this technique in combination with simulation models can increase the reliability of forecasting the results of the participation of radio troops in the repulsion of the air strike enemy. The results presented above indicate the achievement of the purpose of the article and determine the direction of further research on the development of methodological approaches to the study of the survivability of the group of radio troops in the performance of assignments. Tality of radio engineering troops groupment are expounded at the reflection of blow of opponent facilities of air attack.
