https://en.wikipedia.org/wiki/Citadel_of_Aleppo https://en.wikipedia.org/wiki/Citadel_of_Aleppo This ancient fortification was the only thing the Syrian army held in the city for months, if not years. It functioned exactly as an ancient fortress did - providing high ground, spotting enemy movement, safety of supplies, etc. Another recent example is: https://en.wikipedia.org/wiki/Second_Battle_of_Donetsk_Airport https://en.wikipedia.org/wiki/Second_Battle_of_Donetsk_Airpo... This was NOT fortified, but allowed concealment, and was held through heavy bombardment, offering a tactical advantage. Yes, US/Russia/China could pound it into the ground, but that takes a LOT of ordinance. Btw, WW II is FULL of these examples. I think the misconception comes from the fact that "modern weapons" - jets, radars, comm sites, missiles, etc cant be "secured" in these facilities. This is true. But that doesn't mean they can't be held through heavy bombardment and house mortars, snipers, ATGMs, small supply caches, etc.
