Solfège Intel Report:
Satellite intel suggests the Russians have set up a base of sorts in a port city called Kolimbe, population approximately 100k. There is a significant moreau population in Kolimbe. Maybe as much as 15% of the population.
The Russians are not deployed as a single group. And in fact have numerous teams on many missions throughout Etrirea. The Hutus they support number in the thousands but are little more than thugs. Local forces loyal to the NAA number in the hundreds, and while capable of supporting your efforts may prove to be little more than dispensable buffers against enemy attack.
