These flags are for my fictional nation, the Equalist Union. Some were made by finding random flags online and editing them to my taste.
The Land Force is the branch of the Equalist Union responsible for ground based warfare. Members of this branch have received extensive military training. Most members of the land force are of android or transhuman type, with very little humans serving in the army, unless as back up or volunteers. The Land Force fights battles with no qualms about genocide of the enemy. They will fight to win by any means necessary and secure their targets through brutality if it means so. Think like a futuristic North Korea. Usually, those seeking to apply in other branches of the military are required to serve time in the Land Force first as all peoples could perhaps find themselves fighting on the ground first and foremost.
The most extensive branch of the Military of the Equalist Union is the Space Force. Members in the space force are to undertake missions on other planets and in other systems. Mostly for securing resources, defending colony out posts, and engaging in interstellar warfare with other powers. They always fight offensive wars, and never appear 'weak' unless if the situation calls for it. The Space Force is where most members of the military eventually end up serving, and it is considered a duty of all Equalist Union soldiers to serve in the Space Force at some point in their lives. There are some A.I and android roles, although most of it is human and humanoid in nature. The Space Force takes upon any advantage needed, including orbital bombing of civilian and industrial areas of enemy planets and territory, and fighting aggressive unrestricted warfare.
Perhaps the most terrifying branch of the military, the cyber force is responsible for observing all communication on the internet and personal cell devices. They listen to everything that anyone talks about, and have a paramilitary wing that is responsible for arresting and detaining offenders. They have the most power of all the branches of the military and are mostly staffed by human and android staff. They carry out their orders with terrifying brutality. They are also responsible for hacking and doing cyber warfare in other nations networks and military, and spreading propaganda to other nations or communications networks that belong to other powers, installing viruses that hack the mainframes of enemy nations...turning it over to the Cyber Force to examine and judge.
The police are an official branch of the military. Primarily those evaluated to enjoy prying into other people's lives. The police have the power to search anyone's house whenever, and any resistance will result in arrests. There is usually one human officer with a team of 5 androids to carry out the officer's whims. The system is innocent until proven guilty however that usually is a mask, as they collaborate with the Cyber Force in order to arrest and detain people. The Police drive in unmarked humvees with a variety of tools to stop enemy vehicles. They also use lethal and brutal force without any opposition. They are also the enforcers of slavery and take joy in hunting down escaped slaves. They also publicly humiliate offenders. Usually first time offenders are let loose with a stern warning, but those who repeat or do really bad crimes are sold into slavery or into forced manual labor
The Equalist Air force members are also a part of the Space Force, although they are specifically trained as for operation within the atmospheres of planets. They pilot UFOs and other strange craft that are foreign to most people. In wars they participate in gas attacks of enemy armies, drone strikes, and aerial warfare. Sentient drones are also among the air force and can be deployed by aircraft or UFOs. They prefer to be at a distance, observe, and attack from a far rather than engage in open conflict.
The Naval Force of the Equalist Union is responsible for conduction missions in bodies of liquid among planets. They use underwater craft. USOs, instead of typical battleships. The USOS (unidentified submerged objects) can be all sorts of shapes. Sometimes spotted by weird distortions or glowing lights under the water. They are extremely stealthy and prefer to use long range equipment. The people in these craft are under water for long periods of time but the craft they use are larger on the inside and don't conform to Euclidian space so don't get cramped. They also are responsible for the strange sinking of enemy ships. Often, you don't even know you are war at them. When you sink, you have no idea who caused it. You are confused, and you will perish not knowing who was responsible.
The anomalous investigation force is the most mysterious branch. Not even the most senior command know of its existence. It operates by Starlight's direct orders and investigates all anomalous events in space, time, and the paranormal. They investigate all things unknown through any means necessary.
