Explain the difference between direct fire and indirect fire, and give an example use-case for each in COTAC operations.

• A. Direct fire is from a weapon aimed at the target in line of sight (rifle, weapon system); indirect fire uses fire support assets (artillery, mortars) beyond line of sight.
• B. Direct fire uses artillery; indirect fire uses rifles.
• C. Direct fire is always from air assets; indirect fire is naval gunfire.
• D. Direct fire can only be used at night; indirect fire only during day.

Answer: (C)

Direct fire happens when the shooter has the target in line of sight, allowing the weapon to be aimed directly at the target and deliver an immediate effect. Common direct-fire tools include rifles, machine guns, and vehicle-mounted guns, used at ranges where you can see the target and confidently apply fire. In a COTAC operation, direct fire is ideal for quickly suppressing or eliminating an exposed threat that is clearly visible, enabling rapid maneuver or a decisive short-range strike.

Indirect fire, by contrast, is used when the target isn’t visible from the firing position. Fire support assets like artillery, mortars, rockets, or even naval gunfire deliver rounds onto a target through calculated trajectories, coordinated by observers and a fire direction center. A typical COTAC use-case is calling in mortar or artillery fire on an enemy position that is behind terrain or inside cover, shaping the battlefield while friendly forces maneuver.
