Moving vehicles in and out of an AO is only a small portion of logistics. Russia had no problem moving units in and out of their staging areas, and yet they're bogged down in the north and struggling to advance 100 km across the flat Eurasian steppe because they didn't do basic maintenance work on their supply trucks.
Your tanks aren't gonna be doing much shooting if their supply trucks can't get to them because PVT Zhou didn't turn over the tires once a month as preventative measures to keep them in working condition, and now the side walls are rotten and brittle, so they're breaking down the moment they veer slightly off road.
Your infantrymen aren't gonna be humping a whole lot of ammo and equipment if they're eating MRE that expired in 2015 because MAJ Dong decided to skim some profits selling his brigade's fresh MRE to local military enthusiasts for a couple of yuans. Or if COL Ye decided he'd rather buy cheaper, nearly expired pork instead of the more expensive ones, keeping some extra cash for himself. Or if you left your water tanks sitting out in the sun for a week straight and now they're falling apart.
You're not gonna own the night if LTCOL Miao didn't bother to buy enough batteries to actually power NVGs for his enlisted. Or SGT Zhang decided that he doesn't need jumper cables for his jeep.
Any two-bit military can move tanks in and out of an area. Being able to sustain, replenish, and repair those tanks when inevitable breakdowns happen is way more important.
hmm...
IIRC there was the LHD that caught fire while berthed and had to scrapped, a couple of DDs and a sub that just run in to things in middle of the sea, the crash landing of a fighter into the South China Sea, the CV that had its crew infected with Covid and became non-operational.....
Oh mea culpa we aren't talking about those guys
Focus, Chinese examples...
Two fighter jets crashed into the sea near the south eastern coast in an apparent collision, resulting in two deaths. Had to ground all those jets and suspend all training missions, after concerns about training and maintenance
A fighter jet, apparently far superior to the F-35, crashed into the sea while taking part in training exercises. Combat training for the fighter fleet had to be suspended in the aftermath of the crash.
Wonder if it was that Zhang fella at work again or maybe it was Abe or Park, who knows they all look the same
Duh, those are RoCAF examples, Republic of China is still China right? Not that sure because there's this cat lady that calls herself president or something that keeps coming out claiming otherwise and loads of American ex-diplomats keep popping by who go on and on about Taiwan but then the State department seem to contradict them saying there's one China, honest! Well Americans and geography, Iran or was it Ukraine well they're somewhere on the map near to that Africa country!
