IPA: /dɪˌmoʊbɪlaɪˈzeɪʃən/
KK: /dɪˌmoʊbɪlaɪˈzeɪʃən/
The process of disbanding or disarming military forces that were previously organized for active duty, returning them to a state of peace.
After the war, the government focused on the demobilization of troops to help them reintegrate into civilian life.
Demobilization is formed from "de-" (meaning down or away) and "mobilis" (from Latin, meaning movable or capable of movement) and "-ation" (a suffix used to form nouns indicating an action or process). The term refers to the process of taking troops out of active service, effectively making them no longer movable or active in a military context.
Think of 'removing' ('de-') the 'movable' ('mobilis') status of troops, which helps you remember that demobilization means taking soldiers out of active duty.
