This page is a discussion of the US military response to the Posleen Invasion based upon the fictional universe created in John Ringo's Legacy of the Aldenata series of novels.

The initial plan for the defense of the United States against the Posleen was three-tiered: Line, Strike, & Guard units. The collapse of the mobilization plan forced a change to this system. This plan was formulated knowing that the orbital battle would be lost with minor attrition to the Posleen at best.

The Mobilization PlanEdit

The mobilization plan conceived by the Ground Forces command called for a phased induction of civilians (conscription), a recall & medical rejuvenation of veterans, and the expansion of the military. The plan's point of failure was the reliance on the rejuvenation of the mid-level officer & non-commissioned officer grades. When the rejuvenation process bogged down, the military was unable to cease inducting and training recruits due to the short time remaining until the first wave of Posleen invaded. Units were filled with privates without sergeants. The results should have been predictable. Normally, existing units are levied for a cadre to provide leadership until peer-leaders are identified and trained. The bulk of the existing US Army & Marine Corps forces were deployed off-planet to defend Darhel owned worlds in order to generate the revenue needed to pay for Earth's mobilization. The heavy casualties taken by these units on Barwhon & Diess both reduced their quality and prevented them from rotating personnel back to form cadres for the new units. The initial policy of integrating female soldiers into combat units led to extreme casualty rates (except in ACS units). This policy was rescinded. The initial plan for the defense of the United States against the Posleen was three-tiered: Line, Strike, & Guard units. The collapse of the mobilization plan forced a change to this system.

  • Line units were designed for positional defense but could be sent wherever needed.
  • Strike units were essentially cavalry units in a "fire-brigade" role.
  • Guard units were an expansion of the National Guard system used for local defense. In some cases these units were named & numbered as State units, much like the regiments in the Civil War.

Forces were assigned to two commands: Continental Army Command (all US forces on Earth) and Expeditionary Force Command (all off-planet units). Neither command "owned" the Fleet or Fleet Strike.

The Defense PlanEdit

As implemented, the plan called for certain coastal cities (Norfolk, Washington, D.C., San Francisco and New York) to be walled and defended. They were supplied for up to 5 years of siege. When defeat was inevitable the Navy would evacuate the forces. Each city would be supported by one or more "outer fortresses" that would provide enfilade and defilade fire against the Posleen. When the outer fortresses were in danger of being overrun, ACS or Cavalry units would be employed to aid their escape to the mounains. Sacramento would be garrisoned by 5 divisions. The Midwest would be defended by more fortress cities and by the 11th Mobile Infantry Division. It was expected that the Posleen would eventually overrun the Great Plains all the way to Nebraska or South Dakota due to the lack of defensible terrain. Some areas of Colorado were expected to survive because of the Rocky Mountains. This included the old NORAD headquarters bunker in Cheyenne Mountain. The orbital mechanics of the Posleen descent from orbit meant that there would be a concentration on the eastern and western coastlines and that there would be a greater concentration on eastern than western. This drove the disposition of the available forces, as did their state of training. At the time of the 1st landing at Fredericksburg, the units were assessed to be very weak. "Here we have troops that have only had a filled chain of command for five months. Units that were rioting three months ago. Units that are a year behind on scheduled maintenance, almost two years behind on training. Units where half the vehicles break down in the first fifteen miles. Units that will have a hard time holding fixed positions, much less maneuvering"- High Commander General Taylor.

Fleet StrikeEdit

The 4 Marine Corps Divisions, 82nd & 101st Airborne Divisions furnished the bulk of the personnel and units converted to Armored Combat Suit (ACS) units and redesignated as 1st- 4th Mobile Infantry Divisions. Additionally, the 11th Airborne Division & 4 independent regiments (508th, 509th, 555th, and 565th) were reactivated to defend the Continental United States.

  • The Ten Thousand- An expanded unit with leadership cadre from the the 600, expanded and equipped with captured GalTech for assaulting Posleen lines.

US NavyEdit

  • Battleships

The Navy reactivated all remaining Battleships to serve as fire support platforms. The World War II designs (the "fast battleships") used their 16" guns as seaborne artillery to support the ground forces until the front line moved too far inland. The USS Missouri & USS Massachusetts supported the 1st Battle of Washington, where the Missouri sustained heavy damage.

    • USS Texas (BB-35)
    • USS North Carolina (BB-55)
    • USS Massachusetts (BB-59)
    • USS Alabama (BB-60)
    • USS Iowa (BB-61)
    • USS New Jersey (BB-62)
    • USS Missouri (BB-63)
    • USS Wisconsin (BB-64)

  • Cruisers

The Navy reactivated USS Des Moines] (CA-134) & USS Salem to serve as escorts to the Texas, and to provide fire support to the 193rd Infantry Division defending the Panama Canal. The AIDs of the Des Moines & the Salem manifested female avatars: Daisy Mae and Marlene Dietrich respectively.

  • Submarines

Some of the Ohio-class ballistic missile submarines retained their missiles while others had their missiles removed and the spaces converted to carry troops & supplies.

  • Other forces

No information is available at this time about other ship classes.

Planetary Defense BasesEdit

The Planetary Defense Bases (PDB) each contained a surface to space 100mm rail-gun firing depleted uranium blocks. Additionally, the USS Texas (BB-35) was reactivated and her 10 x 14" guns were removed and replaced by 5 planetary defense cannon. She was assigned to the defense of the Panama Canal.
