Ok, I agree there is no Makopa missile as yet, but does that mean the only applications for these choppers are "escort" and landing site security?
Surely, with the change in the forces mandate, I can think of more critical applications where the Rooivalk can make a more substantial contributions. Also, the M23's has a more organized force that the Seleka rebels had in the CAR (Bangui). That might lead to more engaging battles for the UN force, that will surely require air-support (CAS). One can also add the Rooivalk's ability to do night time recon and patrol work, searching for specific targets to be engaged with the 20mil canon.
I've seen lots of footage on Youtube, where the Apaches had this kind of offensive engagements, against the Taliban. They engaged them using their guns, at nite.
I would think that it would be SOP for ATH's to operate in pairs. Therefore, if you only have two (one pair) the commander will be severally limited. One has to consider that you will have maintenance issues as well.
So, all things considered, having only two Rooivalks deployed, is no more than a token gesture, if I may say so!
