Please can I confirm that a M11 move made as a block move, turns as a whole block.  So if the block is turning right, the top right hand base turns and the rest of the block line up adjacent per normal M11.  I assume each UG has to satisfy their formation and minimum depth separately.  They have to remain as a block to make any movements (at the speed of the slowest UG).

Read 2.F:6 8th bullet on page 36 (PDF edition).

Essentially you are correct, although they do not have to remain as a block.  Depending upon the troop types and their starting formation, it may be impossible for them to remain as a block.
