Ahlu sunnah killed off all the most important commanders like the Danab commander,the Haramcad one. Losing your commanders is a bigger problem than losing soldiers. Experienced officers will take time to replace.
In a war u take down the unit commanders first because the foot soldiers below will 1.Disband from the war and flee because they have noone instructing them on the field, 2. It takes a long time to regain commanders but if u kill foot soldiers, it can be resupplied quickly with 6 month training.
Controlling airstrips, hospitals, and road corridors is important so your allies can come in and drop in weapons, medications, reinforcements, treat ur woundd, etc. If this falls to the enemy, your entraped and the enemy will play the siege strategy to wait till u run of ammo, fuel, food, and water.
The general is the one who should set up the 'theater' of war and ensure they're is access to remote 'tuulos' with water points and livestock so the soldiers can retreat to eat and drink safely while the rest are manning air-strips and ports to ensure external access is open to them with their alliances.
Then it's about taking down their 'weaponry' always send a 'armed squad' with an RPG to knock down their large weapons, burn it, never ever use the 'capture' of other army weapons. The weakness is when a peace deal is reached they will ask for their weapons back, but if you burned it, then that is over. The other weakness with capturing their weapon is they may capture it again from u in another assualt but if u burned it, you ensured they 'lost' their armoury forever and there is no chance it will come back.
If ahlul sunnnah is surrounded and about to lose a confrontation, the best strategy is they burn their own weapons and flee, dont let it fall into the hands of the enemy. That's why u see in a proper army under siyad so many burned out tanks on the field. It's better strategy that way at least your enemy doesn't gain anything.
