Imperial Army ( Sith Empire ) The Imperial Army was the ground forces of the Imperial Military of the Sith Empire . It fought against the Galactic Republic during the Great Galactic War , the Cold War , and the Galactic War . They were involved in the Battle of Bothawui where they faced a devastating defeat against the Republic defenders . The Imperial Army was also involved in the Sacking of Coruscant which brought about the Treaty of Coruscant that left both the Empire and the Republic in a state of cold war . History . After fleeing Korriban , the remainder of the Sith Empire stumbled on the jungle world of Dromund Kaas , after drifting in space for years . Once there , the first Grand Moff began a program to make a new Imperial military . He drafted all non - Sith of age into the army and established a training regimen that is still used to this day . Over the years , they carved into the jungles of Dromund Kaas , fighting off its hostile beasts to make room for the Empire ' s new capital city . After the Imperial armada was completed , the Army and Navy were eventually deployed , in what is thought to be the greatest strategic invasion in galactic history , against the Galactic Republic opening the Great Galactic War . A notable failure of the Army engagement was the Sith Empire ' s second attempt at taking Bothawui , where despite vast numbers , greater than the opposition , they failed thanks to the poor strategy of throwing their numbers at the enemy . Since the Cold War their engagements have been reduced to peace keeping , as the Treaty of Coruscant forbids Imperial and Republic engagements , despite this they remain in active duty and are still deployed against the Republic in disputed territory . By the time of the Cold War , the Army could be found in large numbers across Sith Space . Some of the troopers stationed on Korriban were corrupted by the planet ' s dark energies and went psychotic , attacking their own comrades . Organization . The Imperial Army was the ground forces of the Sith Empire , and the soldiers of the Empire typically wore black armor and carried blaster rifles into combat . Ground forces begin live - fire exercises in the jungles of Dromund Kaas within weeks of their enlistment into the military , and even those non - combatants in the military were trained in the use of basic weapons , survival skills , and first aid . The Army also made use of Imperial crawler tank s , walkers , and a number of models of war droids . Imperial heavy troopers were issued full - body black armor crafted from duraplast , with colored markings signifying their unit or special assignments . Their leg armor was specially designed to preserve mobility and to protect from shrapnel , and while their belt housed extra ammunition and grenades for easy access , the armor ' s bracers housed environmental and targeting controls , and the readouts on the suit ' s chest provided medical diagnostics for treating soldiers who were wounded in their armor . Heavy infantry soldiers typically wore about a hundred pounds of armor , and most soldiers carried rifles , sidearms , grenades , and five days of rations . The typical service period for an Imperial soldier was twenty - five to thirty years . Imperial Army rank structure was as follows : Private , Specialist , Corporal , Sergeant , Ensign , Lieutenant , Captain , Major , Colonel , and finally General . The Imperial Army was divided into various subgroups , including :
