The level of ordinance is enough evidence that there is significant outside support. RPG-7s do not grow on trees in Somalia. I hazard to guess an RPG on the black market is also a great expense to anyone who isn't being given one by one of these groups connected to the arms trade in effort to advance their goals or position in some way.
Seems cheap to you and me but that is about the full annual income of someone from somalia. It isn't realistic for an individual to purchase one without external support.
Well it isn't like you can do very much hunting with an RPG-7. Its purpose is to destroy material that you cannot with small arm fire and that sort of limits the intended purpose and customer.
Same reasons as the context of this photo (1). One party would like to advance some geopolitical interest, another party is willing to do it if they are paid and supported as such. No different than any other business deal.
