Presence, reach, and the value of forward basing

Arriving in a region demonstrates reach, while remaining there creates sustained presence. A carrier battle group can display operational ability during a visit, while the forward basing of HMS Montrose in the Persian Gulf showed continuing British interest and availability. A regular presence helps a government claim a place in regional decisions and defend its people's interests. Routine patrol and contact may require a smaller ship than the carrier or amphibious group needed for a serious crisis. The force should match the daily task while a heavier response remains available.
