The Ongoing Struggle Against Insurgency
These officers represent just a portion of the heavy toll Nigeria's military has paid in the fight against Boko Haram and ISWAP. Their sacrifices underscore the persistent challenges of insurgency in the country's northern regions and highlight the resilience and dedication of those who continue to serve on the front lines.
