This weekend I put together a hostile mob for Force on Force (15mm scale). As mentioned previously, I've gone with a two-base approach to represent mobs. This allows for 'column' placement in streets & alleyways, as well as 'broad' placement in open areas. Also the size of the mob can be halved if it suffers significant casualties in the crossfire. In Force on Force Hostile Mobs aren't an actual physical threat to regular forces, but they can raise the Stress Level of units using Taunts. This degrades the combat effectiveness of regulars.
I looked at photos & footage of the sort of messages daubed on placards & banners in African & Middle East protests, & noticed that often the phrases used can read a little odd to native English speakers - hence the bloke holding the "GO OUT USA" sign. For variety I trimmed the placard of the "USC" (United Somali Congress)-supporting man. The guys hauling TVs & a tyre are busy building a barricade.
The miniatures are a mix of Rebel Minis Modern Rioters, & Peter Pig AK 47 Republic Looters. The bloke in the red baseball cap is a Rebel Minis Modern Civilian. He's a bit on the fat side for 1990s Somalia, but I figure he's a USC agitator well-fed on stolen UN food aid. The bases are laser-cut ply from Fenris Games.
