Victory for the Iron Hands 4 – 0. Blitz, Take and hold, None shall Pass, Defend The flag.
A fun and a much closer game than the score was in the end. A couple of lucky shots and bad saving throws made it go my way.
Conclusion:
The Phalanx is tough with a 3+ save
Fighta bombas is very good, Hunters is not

I want more and bigger units
Once again I find myself using the Heavy infantry to hunt down infantry...
Avoiding the Gargant was a good thing (and the fact that he rolled 1 with the TK weapon several times)
I didn't really need the thunderhawks this time but next time I might be facing artillery or similar...
The IH-list feels kind of solid.
Army lists will follow
