It's on the level "The Storm". Preparation - Two or more players are needed (or risk using a grenade jump on solo play). Location At the first beach, players need to destroy two anti-air Wraiths (enemy tanks). Ignore the tanks (you can destroy the enemy Ghosts) and locate a small round like structure. The skull is on top of this structure. Use the Warthog on the beach (or keep the ones you started with) as an extra step to reach the top of the round building. Another player (or deployable cover atop a vehicle) is the best method to add height to one's jump. Note that destroying both Wraiths (by you or by allies) will make the skull diappear.
Enemies love throwing grenades
Should be the same way.
No
