Here's my Isengard Army.
I used Victrix Vikings for the Wildmen of Dunland and I included my Mordor Warg Riders which I also use for... you guessed it, Mordor!
I painted these (GW LOTR ones) about 15 years ago but I did a bit of a rush job with the Victrix Vikings last year. I was a little short on Uruk Scout models so I filled out the unit with some Mordor Orc archers that were extras from my Mordor Army.
The banner tops are just bead thingies from a local craft store. the flags are just print offs from the internet but they are attached to the bases using magnets so I can store more efficiently. Otherwise all of the models are hot-glued to the movement trays which makes for a quick set up and easy storage. I does however, not allow for skirmish games without potentially damaging the trays. I usually put 24 foot models on a base (the pikemen only have 20) and for cavalry and monsters I usually use 9 but oce in a while I cheat and put 8.
I am guilty of giving these guys a basic paint job just to get them on the table all those years ago. I have no plans of revisting this army with a paint brush in the foreseeable future.
I use a homebrew ruleset which has a roll off for priority, then you roll a D6 for each command model (D8 for the General) to determine how many units you can activate and a 'rock, paper, scissors' approach to infantry, cavalry, archers (and their subtypes like War Machines or infantry type). There is a difference in troop quality that is reflected by the points value, but for unit type there is no difference in point cost.
I'll write a seperate post if anyone is interested in the mechanics at a later date.
Anyhow, gotta go to the dentist!
Enjoy!
