How do you surmise that Russia is "world number 1"?
I never really got the logic of ranking countries based on their relative military strength. You can classify them based on relative military power. But any attempt at ranking them, and that too in absolute terms (rather than a comparison based on a certain mission profile or situation), is doomed to fail.
Russia is a well defended land. US and China are just as well defended. However, in terms of global offensive capability, even UK trumps Russia (UK has its entire force oriented towards something like that, where as Russian military is purely focused on border defence and Europe offence). Rankings are relative and highly subjective to the focus of each military and the situation for which you are comparing them.
For some specialist tasks (such as searching for a submarine in a limited area), a French or UK military force will be more suitable than a US, Chinese or Russian military force. However, wherever quantity matters the most (such as searching for a submarine in an entire ocean), US, Russia,China, India become much more "powerful" than any EU military.
Why? Are our TELs inferior in mobility? I used to think that they were all similar enough.
