What type of fire support is typically coordinated with indirect fire requests?

Artillery fire is the type of fire support that is typically coordinated with indirect fire requests. This coordination involves using forward observers or other personnel who are able to identify targets and provide the necessary data to artillery units to deliver fire accurately and effectively on enemy positions. The process requires clear communication of target information, including location, type of target, and desired effects.

Artillery is specifically designed for indirect fire, utilizing high-angle fire to strike targets that are not in the line of sight. This capability allows artillery to engage enemy forces located behind cover or in fortified positions, making it a vital asset on the battlefield.

While aerial bombardment and naval gunfire are also forms of indirect fire, they are not as commonly coordinated with standard artillery requests, which are typically more integrated into ground operations. Direct combat engagement involves frontline troops engaging targets directly rather than relying on indirect fire methods, separating it from the context of artillery coordination. Thus, artillery fire remains the correct answer due to its established role in supporting ground troops through coordinated indirect fire requests.
