Thanks Guys,
I think a valuable lesson for me is that i had 25 Paras in 3 groups, i think i would be better off taging 5x5 as all these units suffered from pinning rather than dying. the two extra squads would absorb some pins or the units could leap-frog each other to the objective.
Paras are espically good in small groups as they make thier morale check without any pins taken into account.
