In the Precision Strike Mission, you gain if you are the second player a CF token for each of your ships.

With Garm you gain command tokens as well.

What if you prefer to start out with command tokens on your ships that isn't a CF token, can you use Garm to replace to gained CF token with something else you find more usefull?

Are are you forced to have the CF token???

I like the Precision Strike Mission, but in my strategy I really don't need the CF token, I prefer another token.

Precision Strike: After deploying fleets, each second players ship gains a token.

Garm: At the start of the first round and the fifth round, each friendly ship may gain a number of command tokens equal to its command value.

So you get the CF tokens during setup. Then, at the start of the first round, you get your Garm tokens. You can keep or discard the CF tokens as per the normal token rules (i.e. you can get rid of them if you want to).
