Russian 152mm Towed in action
Things to be seen.
Long caliber rifled guns.
No electronics
Semi automatic breech (watch those fingers comrade)
Re-used brass powder charge holder. (brass case seems to get a powder charge, primer, and some kind of cap or plug.
Unskilled crew. I don't speak russian so these could be students. Otherwise these are some poorly led, unmotivated, poorly trained crews.
Exactly as you expect conscripts to be.
