Which of the following is NOT one of the three types of wire in the defense?

• A. Protective
• B. Tactical
• C. Communications
• D. Supplementary

Answer: (C)

Wire obstacles in the defense are categorized by purpose into protective, tactical, and supplementary. Protective wire forms the outer barrier to slow or deter direct assault and protect the defended position. Tactical wire is arranged to channel and disrupt the attacker’s advance, guiding them into planned kill zones. Supplementary wire reinforces gaps and adds redundancy where coverage is needed. Communications wire, while used for keeping lines of communication, isn’t part of this defensive obstacle classification. It serves a different function, so it does not fit as one of the three types of wire in the defense.
