I don't know if this is known, but it's something I've been doing in the Snake MU. If you didn't know, throws have 8 frames of invincibility at start up, so if you ever grab Snake after he shoots his mortar you can dthrow or fthrow right before the mortar hits you and you will take no damage. This could work with grenades too, but that would be too hard to do.
