What was the difference about the soldiers at Yele, as well as Yele itself?

When the soldiers bring the boys back to Yele, a village occupied by government soldiers, Ishmael comments that the soldiers and civilians living in the village appear to be having a safe, almost happy life. Only the sight orphans - children whose parents were slain by rebels - dims the mood of the village. The boys begin assisting in daily work routines and believe they have finally found a safe haven. Beah’s nightmares and migraines increase in intensity to the point of debilitating him from time to time, but he makes no mention of it to the village doctor.
