During combat, why is 'Clear Fields of Fire' an essential task?

'Clear Fields of Fire' is an essential task during combat primarily because ensuring there are no obstructions to prevent firing directly relates to the effectiveness of mission execution. When troops have unimpeded lines of fire, they can engage targets more effectively without the worry of obstacles interfering with their weapon systems. This not only enhances their ability to defend their position but also contributes to their overall combat effectiveness and safety.

While improving visibility for targeting is important, the main focus of clearing fields of fire is eliminating physical barriers that could obstruct weapon discharge. Maintaining communication lines and increasing ammunition supply, although vital to combat operations in their own right, do not directly address the immediate tactical requirement of being able to fire upon targets without interference. Clear fields of fire allow for proper engagement of the enemy, maximizing the effectiveness of the unit's firepower.
