What type of mission is used when engaging a planned target that has friendly elements under fire?

The mission designated as Immediate Suppression or Immediate Smoke is specifically intended for situations where there are friendly forces engaged and under enemy fire. This type of mission prioritizes the rapid engagement of the enemy to alleviate pressure on friendly troops, ensuring their safety and allowing them to regroup or maneuver as needed. The focus of this mission is on speed and effectiveness, aiming to neutralize or suppress the threat immediately to protect friendly forces.

In contrast, Adjust Fire requires adjustments based on observations and is not designed for immediate engagement of a threat under direct fire. Suppression usually implies a broader or more sustained effort to limit the effectiveness of enemy forces rather than an urgent response to a specific threat. Fire for Effect (FFE) indicates a more sustained artillery engagement after adjustments have been made, rather than the immediate response required in a situation where friendly troops are in danger. Thus, Immediate Suppression or Immediate Smoke is the correct response, as it is tailored to urgently mitigate the threat while ensuring the safety of friendly forces.
