Germany, Denmark and other countries have indeed donated a lot of winter gear. Still, there are hundreds of thousands people on the frontline, so the gear is mostly supplied by home industry.
The easiest and most reliable way is via the Ukrainian volunteer communities of your country. The organizations which collect and transport donated things act in a transparent and responsible way, providing you with photos from the receiving party.
In the UK, for example, it's https://www.british-ukrainianaid.org
In the US - https://ukraineaidops.org/ and other orgs.
Indeed, they use the tanks in an improved way, so they will probably upgrade these tanks as well: https://nafo.army/@chrisschmitz/110855173124994792
All these missiles have an elaborate security system, and can be launched only by Kremlin orders. All the local warlord can do with the missile is to make a dirty bomb. And by doing so, doom his small country to isolation. So we'll have to make sure that post-Putin officers are interested to dismantle the launch system, and to make sure that local leaders are interested in international cooperation. The leaders of the "Free Nation's League" https://freenationsleague.org/ have already declared that they will get rid of the nuclear weapons.
Dissolution of old empires is just a natural law. All the European empires have already dissolved, and now the last of them crumbles. As old age and death are inevitable, so is the dissolution of archaic empires when new communication technologies make them outdated. So we'll have to deal with this problem, and fortunately the natural processes of rust and decay will be on our side.
Yes, I am looking forward to see all the colonized people free. They are already working toward their freedom: http://freenationsleague.org/ Moreover, due to climate change, there's going to be a huge northward wave of migration - precisely to the Siberian belt that is becoming warm enough for agriculture.
AFAIK, the Soviet nuclear missiles have already rusted down in the nuclear shafts - and nuch fewer modern Russian missiles will also rust down without imperial funding. And all the destitute, deprived people of the current empire will at last be free to develop and prosper.
