What are the four types of mounted/dismounted attacks?

The four types of mounted/dismounted attacks are correctly identified as Line, Wedge, Reverse Wedge, and Right/Left Echelon. These formations serve distinct tactical purposes when engaging an enemy and are designed to optimize combat effectiveness depending on the situation.

The Line formation is effective for maximizing firepower against a frontal enemy position, allowing units to deliver concentrated fire while maintaining a defensive posture. The Wedge formation is advantageous for maneuvering, enabling units to quickly adapt to changes in the battlefield while maintaining command and control. The Reverse Wedge enables units to pull back, taking advantage of cover while remaining ready to counterattack. Finally, the Echelon formations (Right/Left Echelon) provide a means for units to attack an enemy's flank, allowing for flexibility and maximizing the element of surprise.

The other options do not accurately represent the correct types of mounted/dismounted attacks in military tactics. Each serves to enhance the understanding of unit movement and coordination on the battlefield, which is crucial for success in operations.
