Inside the Rise of Major General John Nkoimo, New Deputy Commander of the Kenya Army

Born in Kilgoris, Narok County, Major General John Maison Nkoimo serves as the Deputy Commander of the Kenya Army in the Kenya Defence Forces (KDF).

Over the years, he has built a distinguished military career that spans frontline operations, strategic command and senior leadership roles.

He began his education in Kenya and later joined the military, where he steadily rose through the ranks.

Along the way, he also underwent advanced military training, including reported studies at the Defence Academy of the United Kingdom, which strengthened his leadership and strategic capabilities.

Nkoimo first gained national recognition during Kenya’s military operations in Somalia.

Around 2011–2012, he served as Lieutenant Colonel and commanded the Southern Sector under the African Union Mission in Somalia.

In this role, he led Kenyan troops in major operations against the Al-Shabaab terror group.

As a result, his forces helped capture strategic locations such as Ras Kiamboni and Bur Gabo, which significantly weakened militant control along the Kenya–Somalia border.
