Regardless of the outcome of this Ukrainian incursion, it is a massive failure on the part of Russia to not have noticed an invasion force massing on their border in a country with which they are currently at war. Similar vibes to October 7th failure in Israel in which Hamas managed a surprise attack when nobody thought that was really possible.
The Russian side just seems to continually make unforced errors over and over again and I think they have drastically hurt their reputation as a military power globally.
While some weaknesses have definitely been exposed, chiefly in command and control structures and logistical issues (ie still no aircraft shelters?), I think that part of this feeling is stemming from the western media bias.
For example, there was a lot of hype surrounding the transfer of the GLSDB. The cost effectiveness and range was made out to be something that could saturate Russian defenses, but now the Ukrainian military has discarded it due to Russian EW. The failure, while publicized, is less well-known.
Similarly, there was a lot of hype around the M777 and Excalibur transfer, which again, the latter has been completely neutralized.
We see this story played out continually, AGM-88 HARM, Storm Shadow/SCALP, Western Tanks (Leo2, Abrams), etc. Given that the majority of posters on SDF have a pro-Russian bias, these weapons are routinely derided as "wunderwaffen". However, this isn't too far off the actual portrayal in Western media with headlines like this
My favourite is the Switchblade drone, the hype surrounding it could only be rivaled Segway, Daikatana, Duke Nukem Forever, Zune, and the Arch Deluxe. This is a weapon that the US has spent millions on, and now considers scrap due to Russian EW. For Ukrainians, it is easier to buy parts from Alibaba through Poland and DIY.
