How is a frontal assault defined?

A frontal assault is defined as a direct attack against the enemy's front positions. This tactic involves engaging the enemy head-on, aiming to overwhelm them with force and establish a breakthrough in their defenses. A frontal assault typically occurs when the attacking force believes that they can successfully engage the enemy's positions directly, often relying on superior numbers, firepower, or tactical support to gain an advantage.

In contrast, the other options present different military tactics that are distinct from a frontal assault. A surprise attack from the rear involves flanking or attacking the enemy from a less defended position, which is strategic for exploiting vulnerabilities rather than confronting the enemy's main strength. Long-range artillery bombardment focuses on delivering firepower over distances to weaken the enemy before ground troops engage, rather than an immediate direct confrontation. A siege is a prolonged military blockade, where forces surround an enemy stronghold to cut off supplies and force surrender, rather than an immediate offensive action. Thus, the definition of a frontal assault is well captured by its nature of direct engagement with enemy positions.
