Not all of them. If you think that's true you're extremely naive. Sorry to say. Many of them have, perhaps even the majority, but not all. Many Dhulbahante and Warsangeli soldiers are based currently in Berbera, Hargeise, Baligubadle and other bases.
Nope; check your facts. Over 60 technicals of Dhulloz who were getting paychecks from SL switched sides the moment SL military attacked the traditional elders (Garaado). The Dhulbahante forces were in Sool region mostly, and they become part of the #SSC Defense forces when the battle started.
Men like Hussein Ducaale, Laanta, and many others are at the front, waging the battles against SL forces. In fact, they are a significant part of the forces defending Laascaanood.
The Dhulbahante in Puntland send roughly 70 technicals. Plus the forces led by General Cabdi Madoobe who are from Buuhoodle/Cayn region.
So from a trained military personnel, the combination of these 3 forces are waging the battles against SL forces. Of course, local young men in Laascaanood are also very much participant.
Bottom line, the presence of Dhulbahante and Warsangeli in SL forces is very minimal today.
