Which set of words expands the acronym RACES?

• A. Raid, Ambush, Contact, Economy of force, Security
• B. Raid, Assault, Covert, Escape, Safety
• C. Rally, Ambush, Cover, Economy, Security
• D. Raid, Ambush, Contact, Endurance, Shield

Answer: (A)

RACES is a mnemonic for five basic tactical actions a unit can take in combat operations. Each letter points to a standard term: Raid, Ambush, Contact, Economy of force, and Security. Raid represents a quick, targeted strike; Ambush is a concealed, surprise engagement; Contact means establishing or maintaining communication with the enemy; Economy of force is about allocating limited resources efficiently to achieve the objective without overcommitting; Security is about protecting the force and its information. The set that matches these five terms exactly is Raid, Ambush, Contact, Economy of force, Security, which aligns with the RACES acronym. Other options replace one or more terms with unfamiliar or nonstandard words like Covert, Escape, Safety, or Endurance, which do not fit the established RACES expansion.
