FLAG!

How can I obtain the FLAG badge, I know that it says:
FLAG! - Helped continue the fight against breast cancer
But is there a certain way i need to do things or something else?

PS: I don’t know where I’m meant to ask questions like this, so here I go!

Unfortunately the FLAG! badge is no longer attainable.
From the list of forum badges and their unlock criteria:

> FLAG! - Helped continue the fight against breast cancer. This badge was for participation in the Halo 4 FightLikeA**Girl tournament. (Retired)

There’s a thread at the top of this section with all the badge info. Please check that!
