Short answer: unit 206 and 566 should not be available.

Long answer
Currently the the iraqi army has no minelet arty. As a matter of fact they have not had any artillery at all beyond mortars since the surrender in 2003, the first artillery units are going to be raised in 2009 if they stick to schedule. At this point there is no way to know if and when they will get some scatterable mines in the next decade without using the proverbial crystal ball.
In the past they may have had some limited scatterable mines capacity in the late 80's. They had what is referred to as Ababel/KPTM mine in the american UXO reports, it was seemingly rocket delivered (probably via BM-21 or some other MRLS). As of now I have very little info about the extent it was really an operational weapon.
As I see it you could either delete them (I don't remember any scenario using them) or leave them without formation so that they could eventually be modified into actually used weapons later on.
