As someone who is neutral and has military knowledge I will view this from only the military POV.
1. LasAaanod is a small city with approx. 70k to 80k population and the terrain is very poor for fighting if you have light arms and if you don't have the firepower capability like SL. Somaliland armed forces have logsitical and firepower advantage with a good margin by a galaxy.
2. The Terrain is an open terrain and there is not many places to hide because it is a dry land with not many trees to use as shield hence why there only hope is to use the city itself as labyrinth. Which is why the City got shelled in order to expel the SSC hiding there. They simply don't have the logistical means nor the firepower to go toe to toe with the Somaliland armed forces out in the open. They can max hold within the city few days like 3-4 days but it seems like they only held for 48 hours this time which is next to the maximum..
3. Somaliland doesn't face militarily threat in the Northern regions of the country - Which is one of the reasons Puntland won't get involved because they simply don't have the logistcal means. Somaliland Armed forces have more firepower, logistics, manpower, disciplin.. They can't mobilize many like SL can from only Hargeisa they can mobilize endless cannon fodders on top of having firepower and logistical advantage and these are significiantly large margins which is why Puntland will never intervene or doesn't want any part of this because if they were to miscalculate SL army could march into Garowe and Boosaaso with extremely little effort which is why they failed to take Sool and Sanaag from SL to this day and beaten badly everytime they tried.. Like a walk there is no deterence in Garowe and Boosaaso if they really wanted it they can take it but the only deterence is that they don't want to anger Mogadishu which is why they are sticking with their borders for now but if given the green light from Mogadishu they can annex the entire Bari within days like less then a week
