March Rule, Arthurista!

The Commonwealth Navy is the maritime arm of the Commonwealth Defence Forces, also its most important one from a geopolitical standpoint. It has two primary missions: to prevent the island nation from being invaded or starved into submission. All other considerations, from littoral warfare, amphibious expeditions, power projection to even nuclear deterrence are strictly secondary priorities.

Given its mission, the CN operates in all parts of the world in order to secure the Sea Lanes of Communication ("SLOC") which keeps Arthurista fed and supplied. It is a leading practitioner of anti-submarine warfare, while also possessing considerable capabilities in combined naval-air operations in the open ocean.

As the island's first line of defence, the naval service (including the Commonwealth Marines) has always been regarded as the senior, most prestigious arm of the CDF. Arthurista has always been a major maritime power. As an island, it is only secure to the extent that its shores are safe from invaders and its sea lanes clear for commerce. As of the early 2010s, the CN receives the lion's share of Arthurista's defence budget.

Commonwealth Marines

The Commonwealth Marines are administered by the Commonwealth Navy, although operationally subordinated to higher level army HQs when deployed with army troops. Active units are always manned at 100% strength by volunteer professionals, while territorial reserve formations are composed of ex-active duty marines.

They are organised as elite light infantry, primarily trained in helibourne air assault. However, each brigade has an organic armoured transporter company equipped with 16 articulated bandtracks which enable them to fight as light mechanised infantry. If heavier direct fire support is deemed necessary, armoured units from the Commonwealth Army can be attached where necessary.
