Operation Valiant Shield

Background
Operation Valiant Shield is a large-scale military exercise held across multiple locations in the UW Territory every 4 to 10 years. It initially started of in 2220, after Galactic War 2, to test Earth's Military resolve and coordination in a war-time scenario. It focuses on offensive and defensive strikes, chemical and biological warfare, nuclear attacks and most importantly, Earth's major role in keeping peace among galaxies in the UW Territory.

Operation Valiant Shield 22 (I forgot)

Operation Valiant Shield 2251/52 (to be confirmed) Operation Valiant Shield 2251/52 is the upcoming exercise which will be held mostly near the CU Nations with greater intensity and more units will be deployed. It is predicted that at least 124 trillion personnel, 4,250 naval ships, 21 Carrier Strike Groups(navy), 65 Space Carrier Strike Groups and 4 trillion aircraft will take part in the largest military exercise ever organised by the Earth Armed Forces. It is most likely to cause tensions to strain again between the CU and GATO. Thus, GATO has agreed to be put on battle alert when the exercise commences. It is planned that 20 Space Carrier Strike Groups will arrive at Germanistan before heading towards Salome. Once at the edge of Salome Territorial waters, the Space Carrier Strike Groups will turn back towards GATO. This will be envisioned as a show of force to Salome and prove to them Earth's resolve should they threaten the UW and GATO. In addition, multiple exercises will be held all over GATO and UW Territory with GATO and UW Nations. Those include, amphibious assaults in Zealin Republic, air defense drills, offensive and defensive strikes, missile defense against saturated missile strikes, airborne attack by paratroopers and much more. It is known that Salome may threaten war or even declare war during Valiant Shield and thus, Earth Strategic Command and Earth Armed Forces will be centred at DEFCON 2 throughout Valiant Shield.

Units Involved
A typical operation consists of units from every service branch of the United Federation of Earth Armed Forces, including the U.F.E. Coast Guard. The exercise is usually held with at least 1.2 trllion personnel but can be extended to 324 trillion personnel (which is all the personnel in the U.F.E Armed Forces). As for the navy, up to 1,400 ships or more can be called for active service along with 6 Carrier Strike Groups for the operation and as many as 45 trillion personnel would participate the operation. For the air force, at least 350 million aircraft and 450 billion personnel would be deployed for the operation. The Earth Fleet would contribute at least 6 Carrier Strike Groups and as many as 150 million starships. Usually, the U.F.E. Strategic Command is at DEFCON 3 during the exercise but can always be brought to DEFCON 2 if needed.
