Estonians are just built different

Well generally everyone on joint bases like that reports to the base commander. There’s always a clear chain of command that transcends nations when it comes to NATO operations.

Also, I expect that most small detachments like that are just technical experts, not just straight infantry or anything lol

We laugh but this is not uncommon. I remember reading manpower contributions to the war in Afghanistan back in ‘17 and there were two Estonians and four Icelanders on the list. Hilarious when put next to the 10s of thousands of Americans.
