Right at the check-points of major centers especially at Galkayo right at the border with Galmudug. This will ensure anything entering PL that is dangerous from their side is detected immediately before it enters any towns. A-lot of IED making equipment enters PL thru Erigavo. This will stop it dead in it's track when all vehicles have to pass thru vehicle inspection checks before entering the town. It's only 250-500k per piece.
We need to expand it further into Galkayo around the galmudug border because some of it also enters through there. They target the big towns because they can hide away due to it being very large, they won't try that shit in garowe or qardho or burtinle so the security can be lessened there. That's why it's always good to select a 'small capital' and not a large city.
