What is a significant advantage of successful fire and maneuver techniques?

The choice highlighting the increased likelihood of surprise and success in engagements accurately captures a primary advantage of successful fire and maneuver techniques. These tactics are designed to allow units to effectively engage the enemy while simultaneously maneuvering to gain advantageous positions. By coordinating movement with fire support, troops can create confusion and pressure on the enemy, making it more difficult for them to respond effectively. This combination of tactics leads to enhanced situational awareness and the ability to exploit gaps in the enemy’s defenses, thus improving the chances of a successful outcome during combat engagements.

The other choices, while they may relate to broader tactical considerations, do not directly address the core benefits derived from the integration of fire and maneuver. For instance, while effective communication is beneficial, the tactics themselves are more reliant on the execution of movements and coordinated fire than on reduced communication needs. Similarly, improved morale among troops can result from successful operations but is a secondary effect rather than a direct advantage of fire and maneuver. Enhanced supply line efficiency pertains more to logistical planning than to combat tactics, which the question specifically addresses.
