1) 2nd Armored Brigade Combat Team “Spartan”: The most basic deployable unit was a Brigade Combat Team (BCT). A Tactical Corps BCT had all of the combat and support elements required to self-support in a forward deployed environment. Though in a normal situation, a BCT would have been augmented by detachments from other units (slices) when deployed, most significantly transportation units, the BCT had the bear minimum required to operate on its own.

2) 2-23 Special Troops Battalion “Titan”: The Special Troops Battalion (STB) was the catch all for low density, non-combat jobs. The STB also contained the BCT’s command and staff.

3) Headquarters Company:

4) Battalion Staff: The BCT Commander (O6 Colonel) and Sergeant Major, as well as the staff elements (S1 – human resources and personnel action, S2 – intelligence, S3 – operations, training and planning, S4 – supply and S6 – communications).

5) Military Police Platoon: Platoon of Military Police responsible for the discipline and control of the BCT’s troops.

6) NBC Recon Platoon: Nuclear, Biological and Chemical Platoon (NBC), was responsible for detection of NBC threats, as well as training the BCT’s troops on the use of chemical protective gear and how to operate in an NBC environment.

7) Medical Platoon: Medical team was responsible for routine medical care and combat first aid. Significant combat wounds are treated at a dedicated field hospital.

8) Maintenance Platoon: Was responsible for the repair and maintenance of the light tactical vehicles of the STB.

9) Quartermasters Platoon: Was responsible for material supply to the entire BCT. The Quartermasters Platoon handled everything from beans to bullets. This also included the kitchen staff.

10) Military Intelligence Company: The Military Intelligence Company encompassed Signals Intelligence (SIGINT), Human Intelligence (HUMINT), Measurement and Signature Intelligence (MASINT) and Technical Intelligence (TECHINT) troops. Often, in the case of SIGINT and HUMINT, these troops would be attached directly to the Combat Battalions.

11) Signal Company: Radio communications and computer networks.

12) Engineer Company: Construction combat engineers, plus a Sapper Platoon.

13) 3rd Squadron, 7th Cavalry Regiment “Saber”: 3-7 Cav. Was the eyes and ears of the BCT. This would always be the forward element of any Brigade level attack, making first contact with the enemy and reporting back to the BCT Commander enemy dispositions and strength. As a regiment, 7th Cavalry “Garryowen” traces its lineage back to the 7th Cavalry of the United States Army. After the signing of the Treaty of the Southern Cross, 7th Cavalry was consolidated under the newly reflagged 23rd Infantry Division. Before, it’s Squadrons had been dispersed amongst different divisions within the US Army. The 7th Cavalry was constituted in 1866 and fought in the Indian Wars, World War Two, Vietnam, the Unification War and the Malcontent Uprisings.

14) 3-7 Cav. Headquarters Troop: Command and staff of the squadron. Equipped with two M12 Centaur hover tanks and four M9 Inca Armored Command Carriers (ACCs).

15) A Troop, 3-7 Cav.: A Troop was the Heavy Scout Troop, with four platoons of four M12 Centaur Hover Tanks each, plus two M12s for the Commander and Executive Officer (XO). Depending on the BCT, a Heavy Scout Troop could also be equipped with M21 Anaconda Main Battle Tanks or M23 Highlander Light Tanks in the case of a lighter BCT. VHT-1 Spartas Hover Tanks could be assigned as well, but only as a detachment from the Alpha Tactical Armored Corps (ATAC).

16) B Troop, 3-17 Cav.: B Troop was equipped with M1100 Light Cavalry Vehicles. Though these were had mostly been replaced in other units by M9 Incas by this time, they still soldiered here. Like the Heavy Troop, this troop had four platoons, each with four M1100 LCVs plus two for the Commander and XO. Pairs of M1100s would usually work with pairs of M12s in hunter-killer teams.

17) C Troop, 3-7 Cav.: C Troop was the light cavalry troop, equipped with 26 HC-2 Light Cavalry Hover Cars. Troopers from C Troop would often work independent of the rest of the Squadron, providing deep penetration into the enemy line either mounted or dismounted. Light Troops in other BCTs could also be equipped with M388 Light Cavalry Scout Cars, HMMWVs or HR-32 Hover Cycles.

18) 758th Armor Regiment: The 758th was 2 BCT’s Armor Regiment. It consisted of two active component Battalions, and two reserve Battalions. The Table of Organization and Equipment (TOE) were the same for both active and reserve, with the reserve units co-located on Yellowstone base. The 758th traces its lineage back to the 64th Armor Regiment of the US Army. The 64th was significant in that it was the first tank battalion to be composed of all black soldiers. The 64th was first constituted in 1941 as the 78th Tank Battalion. The name was changed later that year to the 758th Tank Battalion. In 1949, it was re-designated the 64th Armor Regiment. In 2019, with the unit’s reorganization under the UEDF, the unit was re-designated again as the 758th, in honor of the unit’s lineage and to relieve designation conflict with the UN Spacy’s 64th Destroid Regiment.

19) Active Duty Armored Battalions had three companies, each with three platoons of tanks or battloids, plus a Headquarters Platoon. Each platoon had six tanks or battloids, broken up into two sections. The Headquarters Platoon had two tanks or battloids for the Commander and XO. The Company First Sergeant was assigned an M-9 Inca. This gave each Battalion a total strength of 60 combat vehicles, plus two for the Battalion Commander and XO, for a total of 62 tanks of battloids. 1-758 operated the MBR-13 Salamander Main Battle Robot, and 4-758 operated the M-21 Anaconda Main Battle Tank. By the beginning of the Second Robotech War, the M21 was the only main battle tank in service with active duty units, whereas the MBR-13 was starting to be replaced by the MBR-21 Basilisk.

20) Reserve Battalions had the exact same composition as their active duty sister Battalions, only the soldiers were part time, drilling on average one a month with a one month annual training cycle. Reserve units are unique in that the soldiers are all residents of the Member State in which the unit is located, with the exception of company grade (O3) and higher officers, who are full time (Active Duty Reserve). Being full time positions, these officers are assigned under the same policy as the Active Duty UEDF. No more than fifty percent are from the host Member State. 2-758 Armor operated the M-21, while 3-758 Armor used the older M1A4 Abrams Main Battle Tank. After the M21 Anaconda, the M1A4 was the most prolific reserve unit tank in North America. In Europe, the Leopard II was the second most common. Reserve units were also equipped with M10 Aztec Heavy Laser Tanks, but by 2030 almost all of these had been phased out of service.

21) 8th Gurkha Rifles Regiment: The 8 Gurkha was the 2nd BCT’s mechanized infantry regiment. It was composed of two Active Duty Battalions, two Reserve Battalions and two Inactive Battalions. The Active and Reserve both share the same basic TOE. The 8 Gurkha traces its lineage back to the 8 Gurkha Rifles of the Indian Army. The 8 Gurkha Rifles was a Gurkha regiment of the Indian Army comprising Gurkha soldiers of Nepalese origin. The unit was first constituted as the 16th Sylhet Local Battalion, raised in 1824 by the British East India Company. As a UEDF policy, soldiers of Nepalese decent received preferential assignment to Tactical Corps units that traced their lineage back to the Gurkha Regiments of the British and Indian Armies.

22) Each Active Duty Battalion was made up of three line companies and a headquarters company. Each Mechanized Line Company had four platoons, each with 30 dismounted infantrymen and five M-9 Inca Armored Infantry Fighting Vehicles (AIFVs). Each AIFV also had a dedicated driver and gunner/Track Commander (TC), bring the platoons total up to 40 men. The Headquarters Company also two M-9 AIFVs and two M-9 Armored Command Carriers (ACCs) Incas for the command team, four M-9 Inca Armored Mortar Carriers (AMCs) for the Mortar Platoon and four M-304 Amphibious Tactical Support Vehicles for the Scout/Sniper Team. This gave each Battalion a total combat strength of 68 AIFVs and 360 dismounted infantrymen.

23) Each Reserve Battalion was organized the same way as an Active Component Battalion, and was manned the same way as a Reserve Armor Battalion, as above. While 5/8 Gurkha Rifles Battalion (Reserve) was equipped with the same M-9 Incas as its Active Duty sister battalions, 4/8 Gurkha Rifles Battalion (Reserve) was one of the last units to still be equipped with the M2A6 Bradley Infantry Fighting Vehicle. By 2030, almost every active and reserve unit in the UEDF was equipped with either M-9 Incas or M120 Heavy Armored Vehicles. Only a very few reserve units still operated legacy systems such as the M2 Bradley or the Marder IFV.

24) The Inactive Battalions Consisted of a full time Command Team and group of senior Non-Commissioned Officers (NCOs) who filed different staff positions in the BCT. In time of war, they would for the core of a new Battalion drawn up of inactive reservists and new recruits. Equipment would be drawn from either old surplus equipment from the Maintenance and Regeneration Group, or new build items depending on the situation. The time line (theoretically) for standing up an Inactive Battalion was to be six months. In practice, during the Second Robotech War, this process took closer to a year.

25) 1st Heavy Artillery Group “Adige”: The 1st Heavy Artillery Group was organized into three Batteries (in this case, a Group was equivalent to a Battalion, and Battery was equivalent to a Company), plus a headquarters company. Each Battery had a full complement of mobile artillery pieces, as well as fire direction control and forward observer vehicles (FiSTers). The FiSTers were M-9 Inca Fire Support Vehicle (I-FiST). A and B Batteries each had three Sections, each equipped with six M-99 (or Type 99, in the original Japanese nomenclature) 155mm Self-Propelled Howitzers and six Ammunition Carriers, plus a Fire Direction Center (FDC) equipped with M-9 Inca ACCs. C Battery was equipped with the MT-1 Hell Peacock Heavy Armored Multiple Launch Rocket System, in three sections of six each. Though the M-99 and the MT-1 made up the majority of the UEDF’s artillery assets, numbers HWR-00 Monsters and SDR-04 Phalanxes were still in use as late as 2030. These units were mostly on the Moon and Mars, where they served in the Anti-Space Artillery roll, however there were a few HWR-00 Monster Batteries located in Europe, over-watching the Fulda Gap. The 1st Heavy Artillery Group “Adige” traces its lineage back to the Italian Army Artillery Group of the same name.
