What is the primary role of smoke during the breach process?

The primary role of smoke during the breach process is to obscure the enemy's view of the breach site. By using smoke, the assault team can create a visual barrier that hinders the enemy's ability to see the area where the breach is occurring. This obscuration is crucial as it reduces the enemy's ability to target the assaulting forces effectively and allows them to move safely towards the breach without being engaged immediately upon entry.

Additionally, the use of smoke can confuse the enemy regarding the number and the location of friendly forces, adding a layer of tactical advantage to the assault. This strategic advantage is vital in combat scenarios, as maintaining the element of surprise and minimizing enemy fire can significantly increase the likelihood of a successful breach and subsequent entry. Thus, while smoke can serve multiple functions in different contexts, its primary purpose here is to create obscured visual conditions at the breach site.
