It looks like this is a bit like the ECOWAS forces that intervened in Sierra Leone and I think Liberia too. There are a few issues that I am curious about:
1) like
@FaTaL we really need to know who is leading this. In ECOWAS, Nigeria is by and large the big power and Ghana has strong Pan-Africanist credentials. SADC is led by far by SA. EAC has no clear leader. Between Ethiopia, Kenya, Uganda, and Rwanda we have some strong personalities in leaders and relatively strong countries that I am not sure will always play well together. I hope otherwise but we shall see.
2) Given the track record of the EAC in trade and economy harmonization (spotty at best) I'm hoping someone better is managing this. There should have been a robust trade bloc and connecting infrastructure in East Africa decades ago. I would put the EAC in 3rd place at best as far as strong regional organizations behind SADC and ECOWAS.
3) The only places I can see them going into is Somalia which would be good once the AU mandate ends and their forces leave. The big question is will they all agree how to intervene in other places like Burundi or a crisis in Ethiopia.
4) If they conduct regional training exercises, standardize and jointly buy weapons and ammo (hopefully domestically sourced when possible), and generally increase security in the region, this is a win as far as I am concerned.
5) Down the road if the Gulf Arabs or China get greedy, hopefully this force will make them think twice. At least the Arabs. I doubt China is scared of anybody but the US.
