> Ukraine has gotten some advanced stuff like the Javelin, but since 2014 they have been a nation at war that knows their survival depends on having better quality troops
Ukraine battles for their future, because we don't want to return to USSR, which is so loved by Russians.
And BTW, Russia have huge technological advantage, because they have lot more techs than Ukraine.
Basically, in 2014, Ukrainians was only ak-74s, even have not body armor; old artillery (without computers); no military communication.
After that, allies helped lot, mostly US/Britain.
Also Ukrainians repaired old soviet t-64s and armored machines and soviet helicopters, and jets, and air defense.
And Russia have for decades spend huge budgets on create enhanced electronics for soviet weapons, so we where sure, they have advanced tech.
In reality, Russians was not good enough trained to withstand long war, they planned to win in few days, and most their forces was planned to be used as military-police.
But any way, Russians have huge advantage in techs - numbers of tanks, jets, helis, mobile air defense, differ few times.
Best forces landed in Hostomel. Here, very close to Kiev, was very interest battle, officials said about 35 helicopters and few hundreds land troops, and there Ukrainians shot down first ka-52 in this war, also they tried to land few il-76s (I'm not sure, hear that one was also shot down), so stakes was extremely high.
They has been eliminated by few days artillery shooting (and yes, there also destroyed Mriya plane).
As I know, similar battles was at other airports.
Also we seen few saboteurs groups, but fortunately they where small and Ukrainian troops eliminated them with just hand arms.
Most other Russian military mostly kneaded the dirt, or fire on civilian objects, and and does not do any honorable.
