Russia is sending recently mobilized soldiers directly to the front lines without any training in order to buy time to establish a secondary defensive line as UA forces are making steady progress across eastern Ukraine. RU losses are reported to be staggering. The Leningrad strategy of trying to win by sacrificing massive numbers of soldiers seems to be the plan for RU moving forward. It also appears to be an effort to ethinically cleanse troublesome minority groups with RU targeting Tartars, Dargins, etc. for conscription into the cannon fodder brigades and near certain death.
RU has also begun to rely on Iranian drones to replace long range missiles. The Iranian drones are much cheaper, but are reportedly vulnerable to Israeli made defense systems that Ukraine has purchased and can also be shot down using conventional arms. But the clear signal from RU is that they are running out of armaments and money and are going to the military version of Costco to try to maintain strikes on UA forces and civilian targets.
On the front lines, it looks like Ukraine is very close to encircling Lyman. RU wanted to withdraw, but Putin vetoed his generals and made them stay. Lyman is a key supply hub that if captured would deprive RU of rail access to defensive positions on the way to Severodonetsk, which will be the next big battle as UA tries to push RU forces out of Donbas. RU is facing a massive supply chain crisis as retreating forces have left behind billions in equipment and armaments. The converse is that UA forces are actually gaining weaponry as they advance, which gives them a huge advantage on forward movement without having to break to wait long to restock supplies. Once Lyman falls, most of northern Luhansk will quickly fall into UA's hands, setting the stage for the assault on Severodonetsk.
At home in RU, protests against mobilization are getting to the point of near revolt in some provinces like Dagestan. This has top RU acolytes of Putin shaking in their shoes. Despite what various pundits will tell you, RU started this war with Ukraine to make sure that all of the people in its republics and client states (Belarus, Kazakhstan, etc.) understood what would happen if they got out of line. RU's invasion was immediately proceeded by revolts in Belarus and Kazakhstan. RU thought that it could roll over a weak UA government and armed forces by storming Kyiv in the style of the old Soviet invasions to put down the Prague Spring, etc. But UA not only resisted, but is now winning. Mobilization is now the spark that is fueling fires against the central government in Russia because the central government now looks weak and out of touch. The exact opposite effect of what was supposed to happen when RU invade UA.
