Interesting, both said have lost the same in military personnel. Both sides had similar military training and started off using the same weapons. Both sides use the same military tactics, which is not very advanced. Neither side learned or watched what we did in Iraq or Afghanistan. So they both have heavy losses
Of course both sides didn’t lose the same. The Russian losses are at most 1/15 of the other side. I have no idea how the Afghan scenarios are applicable.
When it comes to ground forces, Ukraine only has around 1,117 infantry fighting vehicles, 368 main battle tanks, and 268 armored personnel carriers, whereas Russia has 17,677 infantry fighting vehicles, and 17,370 main battle tanks, and 14,991 armored personnel carriers. The number of aircraft at the disposal of the Russian army was close to 4.2 thousand, while Ukrainian armed forces possessed almost 320 aircraft.
Russian military vastly outnumbers Ukraine military in all aspects including defense budget, active military personnel on duty, fleet size, and other military hardware
Russia has more than 900,000 active military personnel on duty, whereas Ukraine has only 361,000 active military personnel
Russia's military spending in 2020, at $61.7 billion, was ten times more than that of Ukraine's $5.9 billion, as per Stockholm International Peace Research Institute
