Signal Corps - The Army’s AT&T. They keep us talking to each other by providing us with radios, cellular phones and satellite communications.
Ordnance - The Ordnance Corps is responsible for keeping the Army's combat forces moving and shooting - they supply bullets and fix vehicles and equipment.
Air Defense Artillery - They defend the third dimension of the battlefield -- the air and space above -- against incoming enemy aircraft and missiles. Learn more about ADA weapons missions, weapons systems and career opportunities at www.airdefenseartillery.com.
Adjutant General Corps - They are responsible for keeping track of people and ensuring that their records are always kept straight. They also act as the Army’s post office.
Armor* - These are the tanks. The M1A1 main battle tank weighs 70+ tons and can go 42 mph over rough terrain. It also sports a 120mm main gun that’s big enough to stick your fist in the barrel.
Field Artillery - The field artillery is known as the "king of battle" and supports manuever units with lethal and non lethal fires assets. They shoot surface to surface rockets, missiles, and projectiles at the enemy. They can attack ground targets up to 180 miles away.
Infantry* - These are the guys on the ground who get up close to the enemy and fight with rifles, rocket launchers and grenades. They can fight dismounted (on foot) or in Infantry Fighting Vehicles alongside tanks.
Special Forces* - Officers can’t get into Special Forces until they’ve been in the Army at least three years because "SF" takes only the best, brightest, and most experienced soldiers. SF conducts worldwide guerilla and anti-guerilla missions as well as training indigenous soldiers of other nations and helping local people to maintain democracy.
Medical Service Corps - They run hospitals and clinics as patient administrators and provide patient care on the battlefield.
Veterinary Corps - Our veterinarians tend to more than just service members’ pets. They also inspect food before our troops eat it, keep MP working dogs healthy, and deploy all over the world to assist native people in keeping their livestock healthy.
Aviation - We have both fixed-wing airplanes and helicopters. Of the two kinds of helicopters, one hauls people and stuff around to get them where they need to go FAST. The other kind are called "attack helicopters" and they fight mainly against enemy tanks. The Army even has more aircraft than the Air Force.
Chaplain Corps - Chaplains attend to the spiritual needs of our soldiers. They also act as the gauge of a unit’s morale and are in charge of counseling soldiers and their families.
Chemical Corps - They defend the Army against Nuclear, Biological and Chemical weapons.
Civil Affairs - You rarely can go directly into Civil Affairs right out of ROTC. These people use their language fluency and interpersonal skills to provide a liaison between the Army commander and the indigenous people in the area. The vast majority of officers in this branch are in the Army Reserves.
Engineers - They build everything from houses and buildings to bridges and airfields. They also destroy the enemy’s stuff by blowing it up with plastic explosives. In war, they build minefields and trenches to protect friendly troops from the oncoming enemy.
Finance - These people pay us. Lots of money comes in and goes out of the Army, so they have a busy job keeping track of where it goes and who gets paid.
Judge Advocate General Corps - The army's lawyers, working either in prosecuting, defense, or administrative law.
Military Intelligence - They tell the rest of the Army what the enemy is doing and where the enemy’s weakest spot is so we can hit where it hurts them the most and us the least.
Military Police - These are our police officers who keep law and order on base and on the battlefield. Military Police Soldiers are technically proficient in policing activities, corrections/detention operations, police/criminal intelligence operations as well as tactically proficient in combat support operations, area security, stability and civil support operations.
Quartermaster - They plan and direct activities that supply soldiers with food, water, petroleum, repair parts, weapon systems and a multitude of services.
Transportation Corps - This branch ships Army equipment around the world by rail, road or water. In fact, the Army has more ships than the Navy.
