Another trainload of rare T-54, T-55 and T-62 tanks in the Russian army was spotted in one of the cities of Russia. The trainload also transported new 2S19 Msta-S self-propelled guns. The Russian army usually uses T-54, T-55 tanks taken out of storage in rear areas or as mobile artillery, there are almost no videos with them. Usually the crew of the T-54 tank is reduced to three people, the tank's work is adjusted from the UAV.
A lot of the shorter ranged but more mobile or easier to move around artillery has become more relevant nowadays than staying afar and hitting your opponent over 20km, 30km, 40km or so on. It explains why so many long ranged artillery like 155mm units forsake their range advantage and come closer to the front, which gets them drone struck.
The reason for this is that attacks now take place as a multitude of small arrows, ala, small assault groups over a much wider front. There is much less concentration of forces that you can blast a big gun with. Instead you have to respond against multiple surprise creeping assaults that is suddenly here and then there. At this point, response time, after a drone spots the attacking force, not range, is the issue.
Instead of staying back as they used to, drone forces are moved closer to the front to reduce the time they can deal with each assault. For this reason, both towed and self propelled artillery units are also moved further forward, supplemented with tanks working as SPGs, smaller caliber SPGs like the ever popular Gvozdika, towed 122mm and even 105mm howitzers. 82mm and 120mm mortars are more popular and used than ever, as well as self propelled mortars along with vintage anti tank guns, field guns and howitzers.
Doesn't mean long range artillery application is no longer useful. You still have to deal with the reserves that are assembling in the rear. But these force concentrations might be more efficiently dealth with by glide bombs, ballistic rockets and MLRS.
