creating a new, fictional oob

[Zocktan]

i am testing now your weapon-suggestions, i'll let you know what works, but how would you modify the two types of railguns?

a remaining problem is, that their aa weapons (plasma guns and the missiles) are superior, best described with "what flies dies" when it enters the map, this weapons should be also high effective against armoured targets.

next problem i've got is with the organisation:
the posleen are organised like ants, that means 400 dumb soldiers are lead by one normal intelligent. that means as long they got orders to attack, they will attack and they just rout, when their leader dies.

is there a way to build these things in the oob?
