Drudge is just out of it.
Drudge may not know what he is talking about, but neither do you. In order to go to Iraq, one must:
Join the Army - done
Get a commission - done
complete your requisite officer course - ongoing
join your Regiment - will do soon
Regiment gets posted to Iraq - Expected, but hasn't yet happened
Accompany Regiment to Iraq - On approval of MoD (Uncertain)
So, he is on track to go - but remains to be seen.
