Stand and Move are standard orders for commanders. You move a commander in exactly the same way you give orders for a brigade to move.

Union Army Commander	Confederate Corps Commander	Union Divisional Commander

However, the most important order for a commander is "Lead Brigade"

This commander may lead the brigade he is stacked with.

At times a Divisional, Corps or even Army Commander may decide that a brigade is in an important situation and the Commander may decide to take over personal command of the Brigade for a short while.

This will increase the morale of that Brigade whilst the Commander is attached to it. However, whilst this commander is Leading a Brigade its command distance is halved.

This means that units may have difficulty getting their orders whilst their commander is "leading" a brigade. (see command distance). Which may mean other brigades under the immediate command of this commander may not move, and subordinate commanders may not be able to have their command zones changed.

So make sure it is really important enough before attaching any commander. However, whilst a Brigade has a leader attached to it, it will have a much higher morale and thus a greater chance of following your orders (see Morale).
