In tactical operations, which of the following is a benefit of "support by fire"?

"Support by fire" is a military tactic used to provide covering fire to assist maneuvering troops in their advance. This tactic enables one unit to suppress enemy forces while another unit moves into position, thus significantly enhancing combat effectiveness.

The concept revolves around the idea of allowing troops to maneuver safely by offering protection against enemy fire. This means that while one element is engaging the enemy, another can move to a more favorable position, such as to flank or close with the enemy. Consequently, providing cover for movement is a fundamental principle of this tactic.

In the context of this question, the benefit of "support by fire" directly relates to enabling friendly troops to advance without being engaged by enemy fire. The additional benefits related to this action, such as encouraging the enemy to retreat or facilitating artillery strikes, do not fully encapsulate the primary function of support by fire, which is to safeguard movement on the battlefield.
