The DOOP Army (sometimes known as the Earth Army) is the protector of all members of the Democratic Order of Planets, such as Earth. Its motto is "Join the Army, What Are You Chicken?". The Army is often led by legendary 25 Star General Zapp Brannigan and doesn't seem to care about human life, sending wave after wave of its troops to their deaths on often fruitless missions based on decisions that arguably lack tactical credibility. The DOOP Army generally prefers to wage war against weak, undeveloped or defenseless opponents, such as the pacifists of the Gandhi Nebula, or the "weak and womanlike" Spiderians. Whenever confronted with aggressive and technologically developed enemies, such as the Omicronians or Decapodians, the DOOP Army usually suffers crushing defeats due to Zapp Brannigan's moronic tactics.
Men can sign up and drop out at any time, unless, of course, war is declared. Women, however, were forbidden to join the Army before 3008, as they had been known to distract male soldiers, specifically Zapp, with their uniforms. It is likely this restriction has been dropped, though, as two female soldiers are seen on board the Nimbus during the anti-tentacle blockade of Earth. Earthican Robots are implanted with a Patriotism Circuit, which, in case of emergencies, can be activated, forcing them to serve the DOOP Military. The DOOP Army Soldiers wear green uniforms whilst battling on ground, and red uniforms (similar to those of Zapp and Kif Kroker) whilst fighting in space. The troops also get a 5% discount at Earthican stores. New recruits undergo a rigorous training program, often practicing all afternoon before being sent into battle.
The primary assault weapon used for ground troops is the Positron Shooter, a type of ray gun requiring a Jack-In-The-Box style wind-up charging. This charging comes complete with music. The Commander of the Army, Zapp Brannigan, has access to Earth's missiles and other weapons ready to be used during an invasion. The flagship Nimbus is another powerful resource.
