Company / Legends A company was a military ground infantry unit , normally comprising an average of 144 soldiers . Grand Army of the Republic . In the Grand Army of the Republic , a normal company of clone troopers consisted of four platoons , totaling 144 clone troopers , 16 sergeants and 4 lieutenants , led by a Captain . This gave a company a full strength of 165 soldiers , not including support personnel . Four such companies formed a standard battalion . Among the clone commando forces of the Special Operations Brigade , however , a company contained 100 commandos , organized in 5 troops , and five companies formed a Commando Group . Galactic Empire . Imperial Army . Once the Grand Army of the Republic had been reorganized into the Imperial Army , the company of four platoons remained standard , but companies dedicated to specialized roles were now organized differently , with different numbers of troops and equipment . In addition to the four combat platoons , each company was equipped with a dedicated detail of command and support personnel . This made the company the smallest type of unit which could operate autonomously of its parent formation for any extended period of time . The Imperial Army ' s company formation was considered sufficient force for capturing an entire city . The company commander , a Captain , was assisted by a command element of four staff officers of Lieutenant rank designated SC1 through SC4 , along with 23 support personnel and an average of 118 droids . If the company was expected to go on a mission longer in duration than usual or completely isolated from all other support , the support staff would be augmented with additional droids . The company could also be augmented per their standard Order of Battle ( OB ) , in which case the additional units were commanded by the company ' s second - in - command . Line Company . A line company was a standard , run - of - the - mill infantry company , having four line platoons for a total of 152 troopers and 180 personnel total . It could be augmented with two heavy weapons platoons and two additional line platoons . Drop Company . Drop companies were essentially line companies given additional support staff and designed to operate independently on missions of up to six weeks , although two weeks was the standard . The support staff was given additional training for survival in hazardous environments and taught this information to the troopers . Ideally the support staff could keep the company going until they ran out of ammunition , though realistically keeping the company functional after a month on a planet ' s surface was considered a good job . The drop company ' s OB differed from a normal line company in that it could be augmented first with a heavy weapons platoons , then two additional line platoons , and finally an armor platoon . Assault Company ( Heavy Weapons Company ) . This company unit had two assault platoons and two line platoons which , depending on the configuration of the assault platoons , gave it a total strength of 180 to 198 men with 152 to 170 combat troopers . The line platoons in these companies equipped all of their squads with light repeating blasters , though in later years each platoon replaced one of these for a medium repeating blaster to improve firepower flexibility . It could be further augmented two additional assault platoons and two additional line platoons , essentially doubling in size . Repulsorlift Company . Consisting of two line platoons and two repulsorlift platoons , a repulsorlift company totaled 220 men , of which 188 were combat troopers and the rest command and support personnel , along with 22 combat vehicles , 8 support vehicles and a command vehicle . Each of the repulsorlift platoons carried a line platoon for deployment in combat . An augmented company could have first a scout platoon , two additional repulsorlift platoons and then a third line platoon . Scout Company ( Scout Troop ) . A scout troop contained four scout platoons plus the support and command element , for a total of 116 troopers and 40 speeder bikes . The whole command element was mobile , using high - powered command speeders instead of bikes , as was the support element , though the staff was smaller than in other company types and contained fewer droids due to their independent nature , the normal " lean and mean " mentality of scout troops , and the sheer fact they wanted for storage space . Scout troops could be enlarged with four additional scout platoons to double their size . Attack Armor Company . This generalist armored company contained three armor platoons and a heavy weapons repulsorlift platoon . The size of these companies varied from from 200 men , 16 heavy tanks and 9 heavy weapons repulsorlifts to 232 men , 28 light or medium tanks and 9 heavy weapons repulsorlifts . Additionally the company had a modified heavy tank as a command vehicle for the captain which , unlike modified medium command tanks , was expected to perform all functions simultaneously and so featured extra heat extractors . Fully augmented companies had an additional armor platoon , followed by a heavy weapons platoon , a line platoon , and finally a third heavy weapons repulsorlift platoon . Breakthrough Armor Company ( Heavy Armor Company ) . Breakthrough armor companies were designed specifically to penetrate enemy lines , cause havoc in their rear , and seize lightly held objectives until further troops arrived . For this reason they consisted of four armor platoons for a total of 21 or 37 tanks ( depending on the platoon ' s configuration ) , one of which was the captain ' s heavy command tank . Unlike other companies , the support element of this company stayed with the battalion ' s headquarters and did not travel into the combat zone . Since the company was usually cut off from any resupply , their mission profile limited them to operating for a maximum of 72 hours before significant supply problems started rendering them combat ineffective . Four more armor platoons could augment this company to its full size . Artillery Company ( Artillery Battery ) . Artillery companies consisted of four artillery platoons , totally 16 heavy or medium artillery pieces or 32 light artillery pieces . They were smaller than other companies with a total of 152 troopers , 23 support personnel and only 70 droids . Normally requests for fire support were routed through battalion headquarters , although if there was time to plan before a battle a company could be assigned to support several specific platoons in a process known as " grafting . " Request from these platoons went directly to the artillery company ' s captain , who was given discretion to respond to them as he saw fit . An artillery company could be augmented with two heavy weapons squads and two additional artillery platoons . Special Missions Company . Three special mission platoons and an augmented scout platoon made a special missions company . It had a command element of 28 and 136 troops for a personnel total of 160 , although the support staff was usually omitted if the mission was of short duration . The augmented scout platoon was smaller than a normal scout platoon but consisted entirely of scout lances for a total of 22 scouts and just as many speeder bikes . Their bikes were also modified to carry additional spare parts and munitions , and the scouts generally saw far more combat than scout platoons normally saw . Each company could be augmented with two additional special mission platoons and two repulsorlift platoons . These companies were deployed on planets considered hostile to the Empire , even those nominally a part of it , and were expected to operate without much support . In rare instances when it was needed , naval support missions of line size or greater would appear suddenly from hyperspace and launch scores of containers of various sizes which landed at various points on the planet ' s surface . Normally only five contained actual supplies , the rest being decoys , and once received the naval support either left or stayed to provide additional orbital support . Stormtroopers . The Stormtrooper Corps appears to have employed companies of 225 men , as there are references to units of 45 troopers within a company structure ( probably five - squad platoons ) , and to three - company deployments with 540 troopers . Standard stormtrooper battalions , however , are cited as comprising 800 to 820 men , very close to the size of standard line battalions of 810 to 826 men , and it may be that some stormtrooper companies were organized on a four - platoon model , similar to that of comparable Army units . Under the Empire of the Hand , the stormtrooper company structure seems to have undergone some reorganization : by 22 ABY , Aurek Company in the 501st Legion consisted of just forty troopers , divided directly into numbered squads of four men each . Something similar may have persisted in the revitalized Empire of the second century ABY , where it seems that squads were still directly subordinate to company command . Other . Another known company with the Grand Army of the Republic was the Tango Company . The Yuuzhan Vong equivalent of a company was a scourge .
