What is primarily focused on when establishing fields of fire in defense?

Establishing fields of fire in defense primarily focuses on interlocking firing arcs because this concept ensures that the coverage provided by different weapons or units is comprehensive and overlapping. Interlocking firing arcs enhance the overall effectiveness of defensive positions by creating zones where different types of fire can support one another, minimizing gaps that an enemy could exploit. This tactical arrangement allows for improved coordination and maximizes the firepower available to a defending force, providing a more robust defense against an attack.

The importance of interlocking firing arcs cannot be overstated, as they facilitate collective fire on targets while reducing the likelihood of friendly fire incidents. This ensures that defenders can engage an attacking force effectively from multiple angles and with different weapon systems, creating a formidable barrier.

In comparison, camouflage effectiveness, entrenchment depth, and moving troops serve different tactical purposes. Camouflage focuses on concealment from the enemy, which is essential but does not directly impact the fields of fire. Entrenchment depth relates to the physical fortifications of defensive positions and their ability to withstand attacks, while moving troops addresses the dynamic nature of troop positioning but does not influence the static defensive coverage provided by established fields of fire. Thus, interlocking firing arcs stands as the primary focus when determining effective fields of fire in
