Abstract: In the early stages of combat operations, the multi-colored coloring of the uniform served, along with other elements of visualization of the situation, to visually distinguish friendly troops from enemy troops, to separate troops by type and purpose, and not to ensure the secrecy of troops. The issue of camouflage of military equipment and structures, at this stage, has not yet been raised. With the increase in the range and accuracy of weapons, with the advent of automatic weapons, the field military uniform gradually lost the function of identification and acquired the function of camouflage. At first it was a monochromatic khaki coloring, which provides an imitation camouflage function, then a camouflage coloring that adds deforming properties to it. With the advent of military equipment on the battlefield, it had to be painted as well. And later, with the advent of reconnaissance and combat aviation, and other types of long-range weapons, it was necessary to ensure the secrecy of not only the objects of the battlefield, but also the objects of the rear. The article considers the history of the development of methods for increasing the secrecy of personnel through the use of protective coloring of uniforms and equipment. Other aspects of the application of methods for increasing stealth in the optical and other ranges, as well as their development in recent history, are also briefly touched upon.

Abstract: The subject of this research is digitalization of the economy, while the object is the structure of this process. Special attention is given to heterogeneous structure of digitalization process, as well as the impact of its various components upon the real sector. One of the concerns this subject category the expert assessment of the concept of “digital” economy as something integral. At the same time, the analysis indicates that the digitalization of society and economy is a complicated process, and each component influences the processes of production, distribution, and management of the real sector. Unless this fact is not taken into account, the errors in construction of digitalization plans may occur, which substantiates the relevance of the selected topic. Based on the analysis of the problems of digitalization of the economy, management, production and distribution, the article synthesizes the recommendations for clarification of the structure of “digital economy”. The author concludes that “digital economy” should not be viewed as organic whole, since the components have been determined with may differently affect the real production and distribution. The novelty lies in the proposal to view digitalization processes as a composite phenomenon that consists of interrelated, but relatively independent components. Theoretically, such approach would ensure more accurate planning of the development of digital production, the theory of economic management, and personnel training.
