ISOF and ICTF patches

i recently bought these as a set from a goodwill ebay store. There were also other soldier's item for sale, but nothing worth of buying or that would tell more story about it.
Do you know why there is ISOF/2 written, instead of the normal ISOF i usually see? Could it be for their 2nd battalion?

Iraqi Special Operations Force (ISOF) formed its 2nd ISOF Brigade in 2008 - 2009. The 2nd Brigade controls the Regional Commando Battalions and includes a garrison support unit of 766 personnel. These battalions are 440 personnel plus a 60 man support detachment and a Regional Counter-Terrorism Center. The brigade includes the Regional Commando Battalions in Basrah, Mosul, Diyala, and Al Asad.

Nice patches!

Here is my Post 2003, Iraqi Special Operations Command Patch.
Translation above: the Second Special Operations Command
Middle: the Special Operations
The patch has ISOF/2 on it but nowhere in the translation is the word
Force used. Strange.
