FA units can only reinforce like units.

• A. TRUE
• B. FALSE
• C. ONLY WITH WRITTEN AUTHORIZATION
• D. UNSUPPORTED

Answer: (A)

Reinforcing Field Artillery units hinges on keeping fire support cohesive and manageable. When FA units reinforce, sticking with like units ensures compatibility across fire control systems, communications, ammunition supply, and command and control. This alignment keeps fire missions coordinated, reduces the risk of misfires or logistic shortfalls, and simplifies administration under stress. If you were to reinforce a different type of unit, you’d face mismatches in equipment, targeting procedures, and supply chains, which can disrupt the fire plan and slow decision cycles. Therefore, stating that FA units can only reinforce like units is correct. There can be exceptional cases in which cross-type attachments are authorized in writing for specific operations, but those are not the usual rule and depend on the situation.
