Obstacles alone may not be sufficient to stop or destroy a target completely, but they can degrade its mobility. This helps to make firepower more effective. This study examines when using both counter-mobility measures (CM) and firepower effects (JF) together yields greater effectiveness than using them separately. Monte Carlo simulations in MATLAB 2025a were used to compare CM, JF, and CM+JF. The comparison is based on the probability of detection (PD) and the weapon system availability rate (WSAR). Synergy is measured in two ways: (i) Ddiff, which shows how many more targets are destroyed with CM+JF compared to using CM and JF separately, and (ii) the index S, which shows the total effect of CM+JF compared to the sum of the CM and JF effects. The results showed positive synergy in most cases, with 44 of the 50 combinations having a positive lower bound for the 95% confidence intervals of Ddiff.

The study evaluates the effectiveness of water charges for engineer support and EOD operations. These charges combine a small explosive with water to achieve controlled disruption of objects while minimizing collateral damage. The experiments focused on opening wooden crates using detonating cord and 550 ml of water. At least three segments of NP V detonating cord were required to successfully release the closures. The method enables safe inspection of the contents without their complete destruction. Although the results are promising, the procedures are not yet incorporated into the regulations of the Czech Armed Forces and require further research on different configurations.
