Hello everybody, hence this is the first time I'm giving a shot at writing fiction please bear with me for a few chapters as I promise to improve my writing as this story goes.

DISCLAIMER:

I do not own any of the mass effect franchise or other SOASE techs which will be told in the story.

As the title says this is about "Alternate First Contact" fictions which you have read of, And most of them were mostly based on Halo, X-COM, Star Wars, Warhammer, etc… most of them were made humanity made bit too over powered than its council counterparts. At first it was exciting to read them but after seeing the same type of stories again and again. It kinda gets bored, so what I will be doing is merging Humanity's tech with 'Sins Of a Solar Empire' tech without making humans OP.

I humbly welcome critics and grammar nazi's to post their criticism.

Thank you.

In this Chapter I will be dealing with Humanity's codex and their supplements…

CODEX-HUMANITY and the Systems Alliance:

Humans are Bi-Pedal creatures hailed from Planet 'Earth' from the Local Cluster named 'sol'. They are governed by Universal Body named 'Systems Alliance'. Before the Systems Alliance most of the outer colonies were under the control of independent governments. It was formed during the end of the first inter-system war between Sirius System and Epsilon Eridani System. As The War aaged on The Combined fleets from inner systems defeated both Sirius and Epsilon's fleets and forced them to Surrender. As the post-conflict approval paved way to form the Systems Alliance.

The Alliance is now responsible for defending the humanity's colonies and Headquarters resides at Exodus cluster, a massive Argonev-class Starbase with a Huge fleet protecting the system. It houses about 1.3 million population in it.

Military Doctrine:

The Alliance employs variety of novel tactics and unique technology. It's relies on speed and flexibility from Destroyers, corvettes and cruisers. They also use their variety of firepower from Capital ships and Carriers.

Humanity is often regarded as 'sleeping giant' by council as only 3% of humans volunteer for military service. They make up for low numbers with sophisticated technical support in the form of VIs, drones, artillery, and electronic warfare, and emphasis on mobility and individual initiative. Their military doctrine is not based on absorbing and dishing out heavy shocks like the turians and krogan. Rather, they bypass enemy strong points and launch deep into their rear, cutting supply lines and logistics, destroying headquarters and support units, leaving enemies to "wither on the vine".

On defense, the Alliance military lives by Sun Tzu's maxim, "He who tries to defend everything defends nothing." Only token garrisons are placed on their colonies. These are intended for scouting rather than combat, avoiding engagement to observe and report on invaders using drones. However, the Alliance stations powerful fleets at mass relay nexuses so that in the event of an attack they respond with overwhelming force.

System Alliance Ships:

The Humanity managed to harvest energy from antimatter to fuel its weapon and engines, the usage of antimatter is strictly restricted to military doctrine as most civilian craft and used helium-3 as their fuel.

System alliance has a variety of combat vessels in each class they are

1. Corvette

2. Frigate

3. Destroyer

4. Cruiser

5. Capital ship

Corvette:

Corvette is nimble craft of size about 80-150 meters which is larger than a strike craft. It's mostly used to harass enemy ships and specialized in taking out its engines and point defenses. It has two classes they are

1. Shriken corvette

2. Stilat corvette

Shriken corvette has

2 x forward pulse lasers

1 x aft missile Battery

2 x anti-aircraft cannons

Stilat corvette has

2 x forward mini pulse-cannons

2 x anti- aircraft laser defense

1 x aft missile Battery

Corvettes were lightly armored and lightly shielded and were mostly used for patrol and support and escort for heavy cruisers. They use powerful jamming tech to confuse enemies and take advantage of it.

Frigate:

Frigates were once used by SA in their fleets, however after the emergence of Destroyers many of them are decommissioned and some are used for civilian works and Colony Defense forces.

Standard Frigate had one spinal mounted auto-cannon and five laser defenses mounted on the ship, it also has 2 missile batteries mounted at the bow of the ship.

Destroyer:

Destroyers are the nimble and heavy hitters of SA, they are fast ships with extraordinary Firepower deployed to take out enemy cruisers and cripple capital ships, scout enemy positions, support and escort friendly ships.

The typical destroyer has twin heavy hull mounted auto-cannons and a single dorsal mounted pulse laser battery. These destroyer ranges from 250-400 meters in length and have durable low –profile armor and mediocre shields. There is an another version of destroyer called Missile Destroyers deployed to sneak in and deliver missiles at close quarters, they also have a powerful anti-aircraft armaments which makes them ideal to act as leader for wolf packs.

Cruiser:

Cruisers are the Backbone of SA fleet, they are fast ships with high caliber weapons often deployed as a leader of flotillas and they pack excellent firepower. They can carry up to 2 squadron of drone to assist it. Cruiser's area of expertise is very large hence there are several classes of ships are developed.

1. Cielo-class Command Cruiser.

2. Kodiak-class Heavy Cruiser.

3. Percheron-class Light Carrier.

4. Hoshiko-class Support Cruisers.

Cielo-class Command Cruiser:

Cielo-class Command Cruiser is the best choice for you if you want a cruiser as a flagship for your fleet, it excels at offensive support with its Tactical and Targeting Analysis (TATA) computers, at also has wide variety of electronic countermeasures to protect its escorts from danger. It has a two heavy pulse laser as main armament and also secondary armament which includes laser banks at both sides and AA batteries. It is the only cruiser class ship which houses advanced intelligence.

Kodiak-class Heavy Cruiser:

Kodiak-class Heavy Cruiser is the largest and most armored Cruiser present in SA Navy; it is the most powerful ship aside capital ships and can dish out and soaks large amount of damage.

Their powerful engine enables them to be used as hunter packs to chase the fleeing enemies and take them out with their Main armament twin gauss cannons. But they are very vulnerable to corvette and strike craft. They also have secondary heavy auto cannon banks to dish out damage at close ranges.

Percheron-class Light Carrier:

This cruiser takes on the role of carrier, sacrificing weapon power and armor for fighter support. They can carry up to 4 squadron of fighter and a battalion of marine and mechs. While they have point defense laser batteries, they don't have any firepower aside from their strike crafts.

Hoshiko-class Support Cruiser:

This cruiser is the Hoshiko was not designed specifically for combat, but it did find a natural niche in battle due to its unique shape, which offers a near 360 degree launch angle for its droids. Using swarms of unmanned repair drones, the Hoshiko can quickly patch up a damaged vessel and keep it in the fight. They also carry a supply of demolition bots that can wreck havoc on the engines and weapons of even the most heavily armored frigates and cruisers. Crewed by perhaps the most eccentric of the SA roster, the Hoshikos are obsessive tinkerers and take great pride in the unique role they fill and ability to engineer ultimate droids.

Capital Ships:

Capital Ships are the largest ship class in SA with unparalleled firepower with best armor and shields. Capital ships are mostly left to guard important choke points, starbases, relay nexuses. These Ships are rarely deployed in patrols and deployed when only there is an emergency.

Although all capital ships have a powerful spinal mounted cannon except sova class carriers and they have different roles to play in battlefield. Currently there are 4 classes of Capital ships present in SA navy they are:

1. Kol-class Capital Ship.

2. Dunov-class Capital Ship.

3. Marza-class Dreadnought.

4. Sova-class Carrier.

Kol-class Capital Ship:

This ship was first designed after the creation of SA but kept in shelves due to the design was far futuristic to develop them, but after their initial losses in war with the PMC these design were finally given the green sign.

It admirably balances speed, protection and firepower. A Kol Capital ship, with its array of heavy weapons, has a formidable presence in any engagement. Commanded by the best of the SA's officers, they were marshaled to front lines to serve as a devastating weapon of war and a sign of hope for the embattled and weary SA fleets. More than any other warship, the Kol has proven to be instrumental in halting the Traverse PMC advance.

The Kol Capital ship had a spinal mounted rail gun, 4 Linked beam cannons, one long range missile battery, two auto cannons and two pulse cannons at the front, they also had 6 auto cannon batteries at port and 4 auto cannon batteries and a hull mounted gauss cannon. it also used anti aircraft laser defense systems and can carry upto 4 squadron of strike crafts/bombers.

Dunov-class Capital Ship:

After the war with Attican Traverse these ships were designed from the tech used by the Attican Traverse. Although this is a Capital ship it is not designed for a direct combat like kol capital ship but to support the friendly ships by acting as a shield pylon, disabling enemy ships with its ion cannons and boosting friendly ships targeting by its TATA .

This ship had a spinal mounted gauss cannon and two ship to ship missile banks and two linked beam cannon and had seven heavy pulse laser batteries on its both sides, also this has a ion cannon mounted at the port side of the ship. It uses magnetic flux to confuse enemy fighters and bombers and have laser defense system to destroy them. This ship can carry upto three squadron of strikecrafts/bombers.

Marza-class Dreadnought:

This was a modified design of asteroid scuttle ship. With its overwhelming firepower this ship had been nicknamed 'The Dreadnought' this is the SA's offensive capital ship. This ship wreaks havoc in enemy ranks with its impressive firepower. This ship is also the best choice for bombarding enemy planets.

This ship has 10 missile banks, two spinal mounted rail guns, 6 heavy laser batteries on its front side. It also uses 6 auto cannons on its both sides and two auto cannons on aft side. This ship uses laser anti aircraft defense system and have a relative weak armor and shield compared to other capital ships.

Sova-class Carriers:

As they are proven to be an effective countermeasure to pirate incursions, strike craft have been a strong of planetary defense forces for hundreds of years has made a mobile platform for hosting strike craft a necessary one, and the Sova Carrier ably fulfills this role. The most advanced ship-borne manufacturing and repair facilities keep its large dorsal and ventral fighter bays in a near constant state of combat readiness.

This ship class can hold upto 10 squadrons of aircraft and 5 corvettes. They have moderate armor and shield and have several missile banks and laser defenses on it.

These carriers always stay back at the formation launching missiles and fighters to harass enemy ships.

annnnnnnnnd that's a wrap in next chapter we will deal with economy,colony defense forces and timelines.
