I recently go into Armada. As I was over looking to rules I notice they have 3 colors of mission/Objective Cards. Blue Yellow and Green. ( I can't remember what they are in the rules book, going off of a shady memory) and also I noticed the red mission/Objective Cards. I'm assuming they're the same it seems. Also I notice in the bottom right hand corner there is a number or no numbers. Does that number count against your fleet building? As in if you were to play a 400 point match you lose 20 points making it a 380 game?

No.

There are 3 main Mission Card Types.

Red = Assault

Yellow = Defensive

Blue = Navigation

You have to include 1 of each of those colours in your normal Fleet. For if you are second player, 1st player will choose one of them.

The number at the bottom tells you how many points a victory token in the mission is worth , because every mission that has a number there, involves Victory Tokens

It never costs you points to field missions. They are all equal in that regard, and one of each colour is required .

GREEN is the Corellian Conflict missions. They are only played at certain times during the corellian conflict, and are not legal or used in regular play.

Okay. Gotcha thank you
