It's good to know that EVERY target can be hit using 1 sec grenade, so "be quick or be dead" (yeah, I am Iron Maiden fan). :-)
However, some of the targets require using 2 sec grenades, if you are not quick enough and they sit down on the terrain, but you should try to avoid this. The more targets blown in the midair, the better. ;-)
