What is a characteristic of anti-material weapons systems?

Anti-material weapons systems are specifically engineered to disable or destroy equipment rather than engage personnel. This category of weaponry is capable of targeting a variety of materials, such as vehicles, aircraft, weapon systems, and other critical equipment. They are designed to inflict damage on the enemy's logistical support and combat capabilities without necessarily focusing on combatants themselves. This capability makes them essential for undermining the operational efficiency and effectiveness of enemy forces by targeting their resources.

The options that imply a focus on personnel engagement or civilian targets do not align with the fundamental purpose of anti-material systems, which is concentrated on neutralizing equipment to achieve a tactical advantage. Additionally, the notion that they require less training is misleading, as anti-material weapons often necessitate specialized skills and understanding of the systems being engaged to maximize their effectiveness. Thus, option C appropriately reflects the primary objective of anti-material weapons systems.
