How an offshore brigade signals without an ultimatum

How should an ambassador signal that a Marine brigade is offshore without issuing a blunt threat?

Announce a brigade exercise with a neighboring state and invite the other government to observe, allowing the military warning to remain implicit.

A diplomat should avoid bluntly threatening another government with a Marine brigade waiting offshore. Announcing a full-brigade exercise with the neighboring state communicates presence, readiness, and political access. Inviting the target government to observe makes the capability unmistakable while preserving diplomatic room to de-escalate. Amphibious forces can influence a crisis through visible preparedness before anyone commits to combat.
