Loop an action

Hi all

Can someone help me out how you loop an action.

If (((Attacked unit) is in OrcAssaultGroup) Equal to True) then do (Unit Group - Order OrcAssaultGroup to Attack (Attacking unit)) else do (Unit Group - Order OrcAssaultGroup to Attack (Random unit from (Units in Orc Attack BaseCamp <gen>)))

If I'm correct the action says

If a unit of OrcAssaultGroup is under attack then order OrcAssaultgroup to attack the attacking unit otherwise order OrcAssaultGroup to attack a random unit in the region.

So the problem is that I want them to continue there attack after they have destroyed the attacking unit. So my idea was to create a loop but I can't find out how to do it.

Can someone help me out.

Cheers

As long as "Orc Assault Group" and the units in region are naturally hostile they should continue attacking by default.

Unless im missing something?
