[Rules] Fall of Empires/Inf Attacks Rules Questions.

[Champagne]

Fall of Empires, Winter's Battle and Infantry Attacks 2nd ed. 

I am an absolute newbie trying to learn this PzG game system. I rarely play tactical board wargames, and I chose the Infantry Attacks series of games because I am intensely interested in the World War One battles of 1914 and early 1915. 

I have a few rules questions. My first question is regarding the Close Assault section of the Rules. My understanding is that an Infantry Company must BEGIN the Activation phase Adjacent to the hex to be Assaulted. It is illegal to move into the Assault hex from a hex that is not Adjacent. In other words, in Clear Terrain, a Jager infantry company with a movement of 3 must move Adjacent to the Assault hex in one turn. Then in the following turn it must be Activated and then enter the Assault hex. The Jager infantry company cannot legally move into the Assault hex and execute an Assault from 2 or 3 hexes away from the Assault hex. 

Do I understand the Rules correctly? 

Thank you.
