this time I couldn't play but at least I'm happy with my orks since the won another time this time none emerged alive from the battle and the Space marines had varely suffered some loses.
as Ashi pointed in a comment we need to start really learning the rules since even when the game went faster we still are not using terrain and we made another set of mistakes.
after finally getting a pair of tables we arranged armies as follows:
Ashi and his cousing used the SM while hellboy and reingard used the Orks.
both armies deployed in a straight line
Ashi and his cousing decided to hold the line and get some time shooting Orks,
the orks went first but didnt seized the oportunity in the end they ran all their units for 2 turns. before being in assault range.
the interesting pint in the game came when the 2 dreads clashed where the SM dread managed to inmobiliced the Ork dread but in return was destrroyed leaving a fixed weapon platarform.
here was the begining of the end. from here it was just a matter of time before the assalult.
In short a magnificent afternoon with lots of spectactors interested in the game. next time I hope we have some terrain and more painted orks since they are so few points per mini that we havent used all my space marines but more thant used my orks.
