5-9ABY: The New Republic Begins

Galactic Concordance ends hostilities between the Imperial Remnant and the New Republic and sets the stage for a de-escalation of conflict the galaxy hadn’t seen for decades prior. The Remnant is explicitly forbidden from the recruitment and training of Stormtroopers, and the Imperial Academies that fueled the Empire’s navy and ground forces were shuttered, while control of Coruscant is officially ceded to the New Republic and major reparation packages are enacted to ensure former Imperial holdouts lacked the funding that could see them re-organize.
Meanwhile, Mon Mothma’s Military Disarmament Act is formally implemented by the Senate after victory at Jakku: seeking to downsize the former Alliance military by 90%, resources and military assets were slowly disemminated or wound down, instead with the remaining New Republic Navy largely dedicated to training new planetary defence forces for Republic member worlds. We can assume at this point, the Ranger program that we see by the time of The Mandalorian—and that was supposed to be further explored in the scrapped spinoff series Rangers of the New Republic—to act as small, isolated enforcement and response strike teams is also established.
