As an aside, I had been wondering how badly hurt were UAF supply chains. I know there were aviation losses from Russia's opening attacks. Did the UAF also suffer losses to their artillery regiments as well? Would their transport assets have been reduced as well? There's a lot of talk about these longer ranged towed howitzers. I was wondering what did the UAF get to tow them with? Then we start posting, among other things, all these M-113s. I thought that long range artillery wasn't towed directly up to enemy small arms range. I thought they'd be brought up to just out of Orc artillery range. Guess I was wrong. I wasn't positing the M-113 as a battle machine with anti aircraft guns/ anti aircraft missiles/ heavy machine guns/ air search radar/ etc bringing troops into battle. I just wondered if the damned things have a trailer hitch.
If I understood you correctly; there are two groups:
one being e.g. the M777 a towed howitzer - far more precise then the present Russian models the UAF has in use and far more versatile ammo available.
To tow these (100? M777) the UAF have certainly enough wheeled trucks to do the job. Fixed artillery are usually placed around 5-10mls behind a front-line. Thus reducing the firing range by that or whatever distance.
The other one are the self propelled Howitzers, e.g. PzH2000, M-109, or the French Caesar - having the important advantage of shot-change position-shot-and so on with immediate firing effect and almost no range reduction (not so much for the Caesar) - to move a M777 to another designated firing (e.g. 2mls off) emplacement, and to get it operational - takes an experienced crew at least 10-15 minutes. In practical usually 20 minutes.
Additionally a PzH2000 and an MLRS system are very capable/effective in counter artillery fire - due to their range they are able to take out the enemies artillery - a hugely important capability which presently the UAF totally lacks.
In that context; German chancellor Scholz today said;
The German government will supply Artillery radar detecting vehicles to Ukraine.
Most likely due to the PzH2000 and MLRS it will not be the ABRA system but the Cobra system. (detection range around 100km) and can detect up to 40 artillery emplacements within
2 minutes.
IMO systems such as the MLRS, (MARS II) PzH2000 (hopefully not just 11 pieces) and Cobra would indeed be a game-changer for the UAF - coupled with some 400-500 Bradley's - and Putin's present gains - wooosh...
But so far the aquited numbers aren't very inspiring - The USA is agreeing towards 16 and Germany towards 4 MLRS.
The main reason why the UAF want's Western stuff is also likely due to the issue that they are already running into ammo and maintenance problems for their Russian stuff. Already an issue in regards to the UAF Air-force.
