FPV-Piloten des ukrainischen „Phoenix“ -Drohne-Einheiten greifen russische 2S19 MSTA-S selbstfahrende Haubike, einen Panzer, Lastwagen und Infanterie an. Kharkiv Oblast.

At this point im pretty sure that SPGs are easier to destroy than towed guns: With the latter you have to exactly hit the barrel (gun shield would just splitter a little) to take it outta action and even then they can just replace the barrel. Theyre designed to be able to quickly change barrels. A hit to the breech mechanism is hard and the gun emplacements often have nettings to prevent that.

With Mstas just hit the box, theres plenty of stored ammo, propellant, hydraulic fluid and fuel to cause a large fire that will utterly destroy gun and vehicle.
