Noob question before playing

By Mcmanus, in Battles of Westeros

Hey my friend and I were wondering if, when you activate an unity you move with it and attack. Or, you need to move every unit in your turn and then attack.

I think it's, you just need to move all unit before attacking if you are moving multiple units due a card or something special.

Thank you!

Then again I read this and I'm confused:

To attack with an ordered unit, the owning player must have already
completed the movement of all his units ordered during that turn.
The player then performs the following steps for each of his units
attacking this turn:

If you order a single unit, it does any movement first and then attacks. If ordering multiple units, you do all those movements first and then the attacks, before going on to the next player's chance to do an order. The attacks do not have to be in the same order as the units moved. Players take alternate turns ordering a unit or units, using 'Order Tokens' or 'Command Cards'. Cheers!
