I'm trying to figure out the effects of Suppresing Fire action, or rather, when does the Pinning effect end.

If the character fails the test, he becomes Pinned. But what happens in the next round, if the attacker doesn't continue using his actions to perform Suppresing Fire? Is the character still Pinned until he passes the the test, or the effect ends as soon as the attacker stops performing Suppresing Fire?

Thanks.

Pinned until you pass the test, and you only get a +30 bonus if no one is shooting at you, not if they just stop using Suppressive Fire.
