What materials are commonly used in the JLTV's armor?

The correct answer highlights the typical materials used in the armor of the Joint Light Tactical Vehicle (JLTV). The armor typically incorporates composite materials and steel, which work together to provide the necessary levels of protection against a variety of threats, including small arms fire and blast effects from improvised explosive devices (IEDs).

Composite materials are advantageous as they can offer high strength-to-weight ratios, enabling the JLTV to maintain mobility while ensuring crew protection. Steel is often included for its durability and effectiveness against penetration. This combination of materials provides a balance between protection, weight, and performance, ensuring that the JLTV can operate effectively in various combat situations while keeping the crew safe.

Other materials listed do not provide the same combination of properties that are critical for military vehicles. Options like aluminum and carbon fiber offer lightweight qualities but may not provide the same level of ballistic protection. Similarly, while plastic and rubber might have utility in other vehicle components for insulation or minor protection, they are not typically used for armor. Fiberglass and titanium, while strong, do not form the standard combination seen in JLTV armor construction. The focus on composite materials and steel is therefore a key element in designing effective military vehicles like the JLTV.
