Russia has a population of 140M people. They are typically conscripting from poor rural areas. They could do this for years and it wouldnt show.
They're gonna need winter camouflage or else they'll stick out like boogers on a white wall. >

That's the point. They use cannon fodder to see where Ukrainians are shooting from so that the Russian artillery can target them >

except thanks to HIMARS that had kinda been neutralized quite some time ago. Since HIMARS outranges Russian batteries. Ukraine opens up on mobniks, Russia returns fire, maybe the Ukranian artillery is damaged by a lucky shot instead of an inaccurate shell from a worn out Russian barrel, but a nearby HIMARS will counter fire and eliminate the Russian artillery anyway.
Cannon fodder only works to draw out artillery if you don't have counter fire waiting for you. Like a pawn in chess protected from capture by a knight. >

You talking as if there's a HIMARS stationed every few kilometers. >

Between the HIMARS, M270, German MARS and the French M270s, there are absolutely enough to be stationed every 30/40 kilometers >

It's unavoidable, if Russia plans to wage war any longer. >

Yeah but all that has to be levied against what the public and non-wartime economy can bear.
If mobilization is more universal, then it stands to reason even more people will flee and be drafted.  After that who stocks shelves or drives trucks or works in factories?
Without a workforce, Putins blunder starts having very real daily inconveniences for even his most zealous supporters.
