What should commanders concentrate on in military operations?

Commanders should concentrate on concentrating strength against enemy weaknesses because this approach is fundamental to effective military strategy. By identifying and exploiting the vulnerabilities in the enemy's defenses or operations, commanders can create opportunities for decisive action and gain a tactical advantage. This principle is rooted in the military maxim of using a concentrated force to deliver maximum effect against identified weaknesses, enabling a higher likelihood of mission success.

Focusing on enemy weaknesses allows for efficient use of resources and manpower, enabling commanders to achieve objectives more rapidly and with potentially less cost. It aligns with the concept of maneuver warfare, where speed, surprise, and the exploitation of vulnerabilities are crucial. Hence, recognizing and applying this principle supports the broader aim of accomplishing operational goals while maximizing the effectiveness of forces in the field.

While retaining resources, strengthening defenses, and forming alliances can be important actions in certain contexts, they do not directly address the necessity of seizing the initiative through offensive action targeted at the enemy's vulnerabilities, which is essential in military operations. Concentrating strength against weaknesses remains the cornerstone of operational effectiveness and success in combat.
