Intergalactic War

Timeline of Events
- 12th August 2037

The first few bombs had dropped on extraterrestrial targets for the first time in history. Both the Allied and Concur powers had managed to strike back at the alien forces, achieving occasional victories against the Valkaryians.

- 5th October 2037

The inability of both the Allied and Concur powers to halt the advancing Valkaryians was quickly addressed with the formation of the United Earth Defense Corps, a global defense alliance formed by all the countries in the world. Valkaryians were pushed back due to the overwhelming numbers of Human soldiers.

- 23rd March 2038 to 15th June 2038

Overhaul Period
The UEDC introduced a new Nylon-Kevlar uniform, alongside graphene vests, shoulder pauldrons, shin guards, carbon-fiber matte boots and upgraded exoskeletons capable of generating 800N of force when fully utilized. Companies and Battalion structures were re-organized and reformed as well as the introduction of more advanced weaponry such as the Zeus Cannon. Valkaryians were pushed back further as Human armies become more combat efficient and mobile.

- 9th November 2038 to 19th March 2041

Operation Colossus
An unconventional plan to storm the last remaining Valkaryian forces and rid them from this planet for good. A total of 400 million soldiers would be stationed in Turkey and Yemen, poised for the kill. However, Valkaryian reinforcements arrived and managed to turn the tide of war, cutting a swath across the Caucasus, eventually pushing into China and Russia as well as Europe and Africa. Furthermore, a logistics fault occurred which caused many soldiers of the UEDC to either die of starvation/thirst or be abandoned and left for dead. Operation Colossus was deemed a humiliating failure with the loss of 250 million personnel.

The rapid advancement of Valkaryian forces resulted in the collapse of several nations simultaneously. Valkaryian forces have also managed to seize the Suez Canal from Human usage, forcing supply ships to rely on the Pacific or Atlantic Oceans for the fastest possible route where they will be docked off in Japan, China, Spain and France respectively from the USA.

Rules of Warfare
The Geneva Convention only applied to human conflicts, therefore it was not applied during the Intergalactic War.

This resulted in inhumane treatment towards any and all Valkaryian encountered which gave the Ethics Committee a headache as they were trying to enforce rules that were deemed "illogical" by the UEDC troops.

Neither side wanted to use any means of biological or chemical warfare in fear of invoking a similar response from the opposite side.

Pros
Medics are able to operate weaponry without any reason related to self-defense as Valkaryians shoot to kill any Human they see.

Torturing or inhumane treatment towards Valkaryians would go unpunished, enhancing research capabilities.

Any weapon that can be picked up to cause harm to Valkaryians can be used no matter if it burns/dismembers/irradiates/incapacitates them.

Cons
Ill-treatment towards Valkaryians would only spark more aggression towards Humans amongst their comrades. This will decrease the chance of any negotiations possible as well as creating an unrelenting attitude amongst Valkaryian Infantry.

Valkaryians might reciprocate the same treatment towards Humans.

Strategies Involved (Humans)
Upon the supposed "declaration" of war against an alien race. Humanity began hurtling every possible attack plan at the Valkaryians. Military commanders from various nations gathered to discuss strategy which was initially chaotic as no attack strategy was certain to work. Thus, beginning the observation phase.

The observation strategy would only apply if there were any changes to alien assault strategies in order to quickly adapt and counterattack.

Observation Strategy
The idea was to observe and determine Valkaryian assault patterns in the initial stages of battle. This was done through the use of Lethal Autonomous Robot Systems (LARS) so as to prevent any loss of human life.

It was determined that the Valkaryians were prone to surrounding their target and encircling them before closing in and charging for the kill. This behavior, labelled the "Surround and Swallow" or "Pincer Movement" behavior had been observed widely and used almost consistently by the Valkaryian forces. Human commanders then concluded that a breakthrough strategy would be an effective countermeasure to implement amongst the biological combatants.

During the later stages of the war, when Heavy Valkaryian Assault forces arrived, the UEDC had no choice but to use human combatants as cannon fodder to observe new attack strategies and weaknesses.

Breakthrough Strategy
A use of lethal force was required to break through the Alien encirclement, which when, implemented, was used to a devastating degree as it inspired confusion and fear in the enemy. During the first wave of assaults, Valkaryian forces were quickly out-maneuvered by the mobility of human combatants (which was largely due to their exoskeletons) and their firepower. This resulted in the first series of Valkaryians being disoriented and flanked as a fierce fighting force could easily waste their troops.

Overwhelming Numbers
The use of numerical superiority really began to outshine breakthroughs as a large-enough group of Humans could be too big of an area to surround and conquer. This is also the reason why Human Divisions are numbered in the hundreds of thousands.

Holdout Strategy
This technique was used when Human Infantries could no longer advance into enemy territory and will have to dig down and hold their position. Eventually, the Valkaryians would lose their interest in the location. However, this behavior was only prominent in Heavier Valkaryian Forces and ineffective against Lighter units. This strategy was also vulnerable to Anti-Matter Artillery fire.

Strategies Involved (Valkaryians)
Though they were facing off a less advanced foe, the Valkaryians still had to strategize their attacks in order to overcome the Humans.

Intimidation Strategy
Seeing as their opponents were more inclined to surrender during their encounters of bright and loud weapons, the Valkaryians created more weapons which emitted a glow in hopes of intimidating the enemy and causing mass panic. Supersonic rounds were also used to create large sonic booms that are able to emit sounds of up to 170dB. This induces psychological fear in Humans which will cause their battle effectiveness to drop.

Political Strategy
In order to further weaken the UEDC. The Valkaryians have attempted to manipulate and interfere with the political affairs of humanity in order to severely weaken their structure. However, it did not go as planned due to highly encrypted servers and messages Humanity set up, which were impossible for Valkaryians to decrypt.

Orbital Bombardment Strategy
The use of Orbital Cannons stationed in Low-Earth Orbit was used extensively to bombard Human Navies or dense fortifications. While powerful, Orbital Cannons are extremely vulnerable to Anti-Satellite Missile Silos as they have no defense mechanism and once fired, would emit a high concentration of Infrared Rays, making it easy to detect.

Illusion Strategy
Knowing that the Humans possessed the numerical superiority, the Valkaryians had to give an illusion that their attack forces were larger. This was done through the use of multiple rows/waves of infantry marching into battle instead of one, spread out across a chain that would last for at least 7km (4.6mi). This not only creates an illusion of a large attack force, but also disperses their numbers so that they are less vulnerable to Human Artilleries. Other than forming large chains, the Valkaryians would usually charge in with Light Infantry, followed by Heavy Infantry which creates a false sense of security amongst the Human armies thinking that their enemy is ill-equipped.

Precision Assault Strategy
Unable to penetrate the frontline. The Valkaryians resorted to the use of Precision Assaults. The assault will play out as follows:

- Valkaryian troops are deployed from their mothership into a populated area in order to wreak as much havoc as possible

- This will enact a response from the UEDC which will send its troops over to suppress the Valkaryians.

Resulting in the weakening of UEDC logistics and manpower in order to break the frontline.

This strategy was especially affective as the UEDC could not respond quick enough once they detected orbital drop pods entering the atmosphere.
