You can have a Roman ally which will be the way to field the army if you want it to win as much as possible, but as the book isn't out yet I thought I would stick with the pure ROR list, and also never flank march to see how it did. I took all the semi-solids I could and filled the army out with lots of skirmishers. I put in an IC for good measure to try to soldify them a bit more and 3 TCs. I also split the army down with BGs of 4 for 16 of the "fake legionaries" so that there were lots of BGs to absorb those bad skirmishing effects.
The army was as follows IC and 3 TC
Fake legionaries 1 x 8 and 4 x 4 (now rechristened FAKE)
Ellies 2 x 2
Foot LF Jav 3 x 8
Mounted LH Jav 5 x 4 and 1 x 6
Foot LF archers 1 x 8
So 17BGs! but not a single superior in sight!.
We played 3 games on the normal scoring system. They were about 3 hours, so a bit short for this type of army and I found at the end of the games I was getting opportunities starting to emerge to pick on isolated BGs with skirmishers, but hadn't time to finish them off. But even then the results weren't bad
Vs NKE out of period game (not too nice as too many Sup Bws) lost 7-13
vs Later Carthaginain won 16-4
vs Bosporan won 12-8
In the first game the NKE was nicely played and some heroic work by a Bw block (who later in the day toasted legionaries and gauls as well) who made a mess of some HF and Ellies. But at the end there were quite a few vulnerable NKE BGs being swarmed, the camp would have gone had we had one (we both forgot) and not a huge risk to the Numidian army (2 more BGs would have died I reckon but 17 takes some getting to). So another half an hour would have seen it quite inrteresting I suspect. perhaps hauled back to a 10-10.
In the second game the Numdians were close to breaking the enemy army and another half hour probably would have managed it. Several scary moments and lost a BG or two to bad evade roles as usual. Elephants did well and ended up charging Gauls in the rear which made a mess. There was a titanic 8 round LF-LF battle in a piece of rough. My opponent had a cunning plan of rolling CTs and Death Rolls before I shot - which wsa relly annoying when he rolled back ones only for me tot hen MISS!!
In the third game also another half an hour would have been interesting as we were just getting stuck in after drawing the skimish tussle. The Numidians had crushed a Thracian BG and the Bosporan heavy cv had charged and were in combat with numbers against them. I probably was about to lose 2 BGs and Linda perhaps 3 more. But after that the Numdians would probably have come into their own as the LH/LF swarm was pretty good at following up and cleaning up enemy LF/LH.
3 really fun games and 4th from 12 after 3 games. So in a four round comp not a bad place to be. 3 very good games. No beginners but people who had played a game or two and they were already well on the ball with the essentials. NKE army rather a hard opponent to face with Numdians. Very good fun to play against. I would probably change the army to 4 6s for the HF and that's the only change I would make. The rest worked really well.
I would sum them up with two lines...
"Excellent when they ride up shoot and run away; not so good when they ride up shoot and half run away!"
"I'm a legionary, I'm a legionary ... aah sorry afraid not, you can die now!!"
Hope they invite me next year as it was much fun
So with that in mind noe.........I would take 6s because then you can put them in column and expand out fully in one go. There are losts of spare LF so I decided my ideal deployment was this x 2 inthe centre, as far back as possible with 2 generals there and 2 with the skirmish swarm. They are a BL bound by the Psiloi and can advance and expand left or right. My design now altered to fit this tactical plan. I think its a very fair reflection of the way a good general might use such an army to keep some flex.
