Leaders and River Crossing

[Poor Yorek]

I'd submit that:

• a Leader could move with any unit it (the leader) activated that made its crossing number 5.0 & 5.72; 5.73. 
  
• a Leader moving by himself would use foot movement rules to cross a major river (5.72. 5.73).  
  
• Should the assisting ENG cross, a leader could cross with it (extension of first bullet).
  

Note 5.72 explicitly states that "no unit may cross a major river at any spot other than a bridge or ford unless an ENG or via assistance of an ENG."
