Yes, its included in both version 1 and version 2 of the rule book. The national capabilites chart list things like the number of red / black cards in that nation's OBA draw pile, etc. its on the back of the chapter A divider IIRC.
Another way to tell... Most nations have Elite (marked with an "E") First line (marked with a "1"), Second Line (marked with a "2"), etc. When a nation has mulitple first line (Russian 447 / 527) or elite (German 548 / 468 / etc) then the letter or number is in a cirlce or square...
The point of all this? The Squads with a square box around the "E" use the half squads with the square box around the "E".
As far as ELR - no number can go "up" - so a 527 Russian becomes a conscript. A 468 becomes a 467, etc.
