Finland has only a very tiny & pathetically weak military and most of the equipment is decades old cold war era junk that probably doesn't even work anymore. USA is forced to open 15 new military bases in Finland and deploy 10s of thousands troops to Finland for Finland's protection.
US troops are there in case Russia decides to create a land bridge to Kaliningrad, by attacking Lithuania or Poland. They are there for the purpose of attack, not defence.
