Ministry of Defense

"The Helldivers recieve their orders from the Ministry of Defence, and I mine from the Ministry of Truth. In this way, the hands of Liberty are intertwined." The Ministry of Defence (MoD) is an executive ministerial department of Super Earth. It is responsible for providing, managing and maintaining the military forces needed to deter and wage war as well as protect the security of the federation.

Collectively referred to as S.E.A.F (Super Earth Armed Forces), the defenders of the Federation are split into different branches, including the Super Earth Army, the Navy, Colonial Guard and of course the Helldiver Corps, whom receive their orders directly from High Command.

Super Earth Army
""Eulogy template - Soldier, Exemplary Service 121: The heoism of [Rank] [Name] cannot be understated. They did not lose their life in the defence of Super Earth. They gave it, willingly."" "Eulogy Template - Soldier, friendly fire variation 016: [Name] devoted many hours to the prosperity of Super Earth. They may rest easy in the knowledge that the [bullets/shrapnel/concussive force] that took their life was Democratic in origin and fired in the service of Liberty."" Whilst the Helldivers are the scalpel of the military might of Super Earth, the regular army corps are it's hammer, responsible for the bulk of the fighting in the galactic war, as well as taking over more permanent security duties over liberated planets. Whilst the exact strength of the Army Corps is highly classified, the army likely possesses vast reserves of manpower numbering in the tens of millions, as they can hold multiple fronts on dozens of planets. The Army also possesses overwhelming firepower in the form of heavy artillery, ICBM and SAM sites, as well as armored vehicles such as exosuits and tanks (the latter of which the automatons have made inferior copies). Additionally, the army is the branch which the Helldivers are drafted from, at least during the first galactic war.

The Army also possesses it's own Engineering corps, responsible for building various SEAF instillation's, such as the TCS Towers and the Orbital Defenses of the Menkent Line.

Super Earth Navy
Super Earth's Aerospace service branch, responsible for maintaining and crewing it's space borne warships like the Super Destroyer as well as aircraft such as the Pelican and Eagle. It's primary mission is to defend and spread freedom, economic prosperity by providing orbital support to SEAF forces planet side, maintain orbital dominance, keeping the Faster than Light Lanes open as well as transporting military personnel and equipment. Though figures of it's exact size is unclear, it is likely the Galaxy's most powerful navy as well as the largest, at least in terms of sheer numbers with over 450,000 active vessels (based on Helldiver numbers as each active diver gets a Super Destroyer).

Colonial Defense Force
""EMERGENCY WARNING: Hostile forces incoming. Evacuate immedately. EMERGENCY WARNING: Hostile forces incoming. Evacuate immedately.""

Possible SEAF Doctrine (speculation)
"The Galactic War is a united effort. Only by working together can we ensure planets don't fall to the enemy." Despite possessing deep manpower reserves and awesome firepower, SEAF forces are often outnumbered, outgunned or outclassed by the various enemies of Super Earth resulting in them being slowly being worn down. Although the exact doctrine of SEAF forces is unclear classified, one possible stratagem employed is a "Hammer and Scalpel" strategy that relies on cooperation between all branches. The Super Earth Army holds the frontlines, enduring the full might of enemy forces, whilst the Helldivers -- with orbital support from the Navy -- deploy deep behind enemy lines where they cripple key objectives, disrupt enemy logistics and cause general chaos. This gives the Army the chance to push forward and liberate some ground, increasing a planet's liberation progress. Once all enemy resistance has collapsed and all ground is taken, the planet will be officially liberated, with SEAF forces then transitioning to occupation, cleanup and reconstruction operations in the aftermath.
