> Russia may have more artillery tubes, but they have a shortage of precision guided ammunition and are having trouble manufacturing more.
This is incorrect, and the Russians have easier logistics than the Western Ukrainians, because the Russians are only fielding Russian arty systems, and the Western Ukrainians have a mishmash of polish, soviet, US, French, and others.
To quote someone from the US Defense establishment, Thomas A. Callaghan Jr., “Quantity has a Quality All Its Own". This is doubly true with area of effect weaponry like massed artillery fires.
> They're basically using it as fast as they can make it just to hold the current lines
They are currently winning a war of attrition. The Russian army is specifically designed for this type of warfare.
> and have been unable to build up the stockpiles that would be needed for another offensive.
If you are attriting an enemy at good odds, there is no need for an offensive. Key defensive points like Mariupol and Bakhmut have been taken.
Given the artillery supremacy, there is little chance the Western Ukrainians will be able to break out, and the Russian defensive lines are prepped just in case.
> Meanwhile PGM deliveries to Ukraine have been accelerating.
Precision guided munitions (HIMAR launched Guided Multiple Launch Rocket System (all variants), Army Tactical Missile System (ATACMS) (80% GPS guided) , Storm Shadows, as well as Precision guided bombs like JDAMs) are inaccurate when they encounter the wide GPS jamming which is now happening across much of Ukraine. Given how much of the HIMAR launched missiles are GPS guided in a GPS jammed environment, they are not very accurate.
Furthermore, the Russians have S400 and S500 air defense, the very best AD system in the world, and they regularly are shooting down PGMs.
If we think strategically about this war
Surveillance: equal (assumes access to US Spy satellites assisting Western Ukrainians)
Intelligence: equal (assumes full access to Western capabilities)
Battle Management: favors Western Ukrainians due to full access to US systems & fusion capabilities
Logistics: favors Russians heavily due to simplified support/maintenance
Artillery: Between 6:1 and 10:1 favoring of Russians
Air Defense: favors Russians
Infantry: favors Russians due to massive reserves
Armor: favors Russians, latest MBTs employed on Russian side
Drones: favors Russians, DJI directly supporting Russians, latest & greatest in Russian stockpile, Iranian support
Aeronautics: favors Russians, regularly dropping FAB500 and greater PGMs
Missiles: favors Russians due to hypersonic missiles and greater missile supply
Electronic Warfare: favors Russians due to full access to Russian EW systems, GPS jammed environment
