Personal body armor has evolved to address threats typical of contemporary warfare. Artillery effects, particularly fragmentation, have become a significant threat to military personnel, increasing the demand for effective protective solutions. This paper proposes a combined analytical–experimental framework for evaluating the effectiveness of personal body armor against artillery fragmentation. Fragmentation characteristics are examined using mathematical modeling and analytical methods. Additionally, existing body armor evaluation standards and testing methods are reviewed. The results indicate that fragmentation represents the dominant lethal mechanism of artillery fire. Although the V50 ballistic test is commonly used to assess fragment resistance, it does not provide a comprehensive evaluation of real-world protection effectiveness. These findings highlight the need for more advanced and realistic assessment methods.

Handheld optoelectronic devices are a key element in target acquisition in current military operations, especially for artillery reconnaissance and infantry reconnaissance units. This article focuses on a comparative evaluation of two optoelectronic devices of different performance classes, MOSKITO TI+ and JIM COMPACT, both manufactured by Safran Vectronix. The aim of the study is to assess whether the higher technical level of JIM COMPACT leads to a measurable improvement in target location accuracy under various field conditions. Measurements were performed under both ideal and deteriorated conditions (reduced visibility, adverse atmospheric effects) using standardized methodology with reference coordinates determined by geodetic methods. Preliminary results confirm a consistent difference in target localization accuracy between the two devices, with JIM COMPACT demonstrating lower dispersion and higher angular measurement stability, particularly at longer distances and in conditions where orientation accuracy becomes operationally critical.
