What type of artillery rounds are known for high angle fire capabilities?

Guided Excalibur rounds are known for their high angle fire capabilities primarily because they are precision-guided munitions that can be fired at steep angles to hit targets with high accuracy. The Excalibur round uses GPS guidance, allowing for effective engagement of targets located beyond typical direct fire ranges and in challenging terrains where high angle fire might be necessary. This capability makes Excalibur rounds particularly beneficial for joint operations and complex battlefield scenarios where both precision and elevation can be critical to minimize collateral damage and maximize effectiveness against enemy positions.

In contrast, standard HE rounds are typically designed for flat or low angle fire and do not possess the precision guidance technology that Excalibur has. Illumination rounds are used mainly to light up areas for observation and targeting rather than to engage in a high angle fire role. Practice rounds serve training purposes and do not have operational capabilities real munitions do, such as guidance or a functional explosive charge. This context highlights why guided Excalibur rounds specifically excel as high angle fire munitions.
