Tea is pretty serious business in the Baltic and Slavic countries. Having to wait for your tea water to boil and THEN heat up your main would be barbaric!
I like that they don't skimp on things like that too. I am sure in a cold climate you can never have enough fuel tabs for heating, and by being generous with stuff that costs nearly nothing like FRH's and stamped and cut tiny aluminum squares the troops don't have to do things like the Americans in 'nam did like pulling the C-4 out of claymore mines and cutting a hunk off to burn as fuel for improvised stoves.
