Hey GoldenApple ... you discovered the secret of melee exploiting.
He spawned left behind your lines ... unfortunately one of his melee doesn't get supressed so he can throw grenades.
You might want to try ... it is not fair but easy to do.
Still waiting for Con to fix it.
I believe you are wrong. The first nade is thrown at 51 seconds , by which time all 3 people have to be suppressed
