What is the first step in the fundamentals of breaching operations?

The first step in the fundamentals of breaching operations is suppression. This step is crucial because it involves neutralizing or minimizing the enemy's capability to engage friendly forces during the breach. By suppressing the enemy, friendly forces can create a safer environment to carry out subsequent steps in the breaching operation, such as securing the breach point and reducing obstacles.

Successfully suppressing the enemy allows breaching units to maintain the element of surprise and manage the engagement area more effectively. It is a foundational aspect of ensuring that forces can breach barriers or obstacles without facing immediate and significant resistance. In breaching operations, the objective is to allow safe movement for personnel and equipment through the obstacle, making the suppression of enemy forces an essential priority before any other actions can take place.
