Osea's Defense Forces are regarded as the most powerful militaries in the world, with significant technological advantages over their Eastern peers and larger than their Western allies. With an emphasis on rapid, global mobility, the Defense Forces are a key component in projecting Osean dominance worldwide in addition to their stated defensive mission.
Osea Air Defense Force
OADF F-22A Raptors
The OADF operates 2/3 of Osea's military aviation assets, and is responsible for a variety of roles including strategic deterrence, homeland air sovereignty, and strategic and tactical airlift of Army and Maritime Defense assets.
The OADF has suffered severe cuts in the post-Cold War era, losing much of its strategic bomber, missile, and airlift capabilities. Its current composition is geared toward attaining and maintaining air dominance with F-22 and F-15 fighters before providing close air support to ground forces with attackers and tactical bombers. It performed well in the Circum-Pacific War, but its primarily 4th Generation inventory demonstrated vulnerability to matured 4th Generation aircraft in the Yuktobanian arsenal as well as 5th Generation prototypes.
Osean Army
Osean Army Rangers
The Osean Army's history goes back to the Royalist era, and many of its units trace their lineage to regiments that revolted in support of the Long Congress in the Revolution.
Despite being a conscripted service until the middle of the 20th Century, the Osean Army has grown to become a professional and sophisticated fighting force, especially following its reforms after the Clavican War. Tactical losses in the Circum-Pacific War were rare until the Battle of Cinigrad. The Army had placed extra emphasis on MOUT training in the years following that conflict, but opponents of this move claim that it has made the Army less competent in open field engagements that are common against near-peers.
Osea Maritime Defense Force
OMDF F-14 Tomcats
With a heavy emphasis on carrierborne aviation, the OMDF exerts Osean control over the Ceres, Pacific, and Atlantic Oceans using the world's most numerous fleet of aircraft carriers. Osea first recognized the true value of naval capabilities during its Civil War, when amphibious landings allowed the Federal Marines to effectively flank defenders on the Califia Peninsula, and later in the Sapino-Osean War when control over Comona and the Futuro Canal granted the Navy a longer reach. The Navy's focus on aircraft carriers came during the Eastern War, in response to Verusa's own naval aviation capabilities.
In the Cold War and modern era, the OMDF has remained essentially a force of aircraft carriers and escorts for them, in addition to comparatively small SSBN complement. Osea's adversaries have recognized this as a potential weakness and built up carrier-killing assets in their own forces, resulting in the loss of two Kingfisher class CVs in the Belkan War and four Hubert class CVNs in the Circum-Pacific War. Rather than deterring the OMDF, the vulnerability of its CVNs prompted development of the more heavily-defended Anderson class Seabase.
