Which of the following materials may not be used to construct boats and craft that are used as a force protection or anti-terrorism assets?

The selection of materials for constructing boats and craft intended for force protection or anti-terrorism purposes is governed by several criteria, including durability, strength, stealth, and the ability to withstand impact. Wood, while a traditional boat-building material, may not be ideal for modern applications involving advanced combat and protection scenarios.

Metal, plastic, and fiberglass possess attributes such as high strength-to-weight ratios, resistance to corrosive marine environments, and superior durability, making them suitable for crafts that need to endure demanding operational conditions. These materials also allow for better integration of defensive features compared to wood. On the other hand, wood is more susceptible to damage under stressful conditions, such as collisions or exposure to corrosive elements, and does not offer the same level of protective capability as the other materials.

Wood's limitations in modern technology and design, combined with its potential vulnerabilities, are key reasons why it may not be deemed suitable for constructing assets directly involved in force protection or anti-terrorism efforts.
