How many phases are involved in the development of soft body armor?

• A. 2
• B. 4
• C. 3
• D. 5

Answer: (B)

Soft body armor development is typically organized into four distinct phases. First, design and materials selection focus on meeting the required ballistic protection, weight, flexibility, and comfort, choosing fabrics and construction techniques that achieve the target NIJ level. Second, prototyping and ballistic testing verify that the chosen design meets performance standards and durability, with iterative refinements based on test results. Third, manufacturing and quality assurance establish consistent production processes, ensuring uniform layer counts, stitching, and overall build quality. Fourth, field deployment and ongoing maintenance evaluate real-world performance, provide user fit and wear testing, and plan for scheduled replacements and updates as threats or standards evolve.

Choosing four reflects a complete development cycle from concept through deployment and lifecycle management. Fewer phases would omit essential steps like production quality control or field evaluation, while more phases would imply additional steps not typically defined in this standard development model.
