Rival security teams?

There were several warlords in Liberia's civil war, and scuttlebutt claimed that various senators and representatives still owed allegiance to this one or that one, and were serving the warlords' interests in peace as they had in war. Darker rumors said that most of the weapons were buried in easily recoverable caches.

I'd have thought that the various police and military groups would be similarly loaded with "former" partisans, but perhaps events like this fight between officers of different security groups indicates that different groups are actually partitioned between different "former" partisans. Or maybe there was just some tribal argument. Or better still, some complaint about precedence in the parade.
