Of course, as
@imei2012 has intimated, it's going to be Rangers and/or other spec ops support like intelligence, medical e.t.c.
The question you should be asking is, who is this who has been supporting those guerillas for all these years? Why do they continue doing it up to date? With such financial muscle, what is stopping them from funding al shabab to keep KDF busy?
You should acquaint yourself with African defence circles. SA, with one of the best spec ops services and air assets, have been there for years and they haven't made progress. What difference will Kenya make when Uganda and Rwanda next door have vested interests?
