Which units can conduct a screen?

• A. All
• B. Only infantry
• C. Only cavalry
• D. Only engineers

Answer: (A)

Screening is a security action where a unit moves forward of the main body to observe the enemy, report what it sees, and delay or disrupt pursuit, thereby protecting the main force’s movement and position. The critical point is not the unit’s branch but its ability to observe, maneuver, and maintain security under a given mission. Because any unit that can perform reconnaissance and provide security can be assigned this role, all units, if tasked accordingly, can conduct a screen. In practice, cavalry and infantry are common screeners due to mobility and persistence, but engineers can screen as well when protecting routes or obstacles. Restricting screening to a single type would ignore the fundamental requirement of capability and assignment, so all units are capable of conducting a screen.
