Here's the best shot I could manage tonight (before my camera ran out) of my British Naval Landing Party for into the Heart of Africa.

I usually run:
1 Regular Leader (Disciplinarian)
5 Regulars
6 Regulars
6 Soldiers
14 Askaris
1 Scout
1 Standard Bearer
1 Machine Gun
Which comes in just over of 600points (500points + 20% extra for being a colonial power).
I find the regulars are very tough nuts to crack (especially with the leader nearby), but a short range ambush or lucky volley can soon put pays to them. The machine gun is highly feared in our group, but has yet to really impress, usually being out-maneuvered due to its lack of mobility. The askaris are very much a meat shield, though if they can get all 14 shooting at a target they have caused a lot of casualties. The scout (Tarzan) is probably one of the most hated units, the ability to quick march a column of troops really makes up for the slow pace of the army and can cause some surprises, in one game he charged a ML Cannon by himself, catching the Ruga-Ruga player completely off guard!
