By Ossoona i guess you mean camo-elite?
Ossoona is a Covenant Sangheili (Elite) title and rank granted to certain Elites that are given Active Camoflague and sent on espionage missions.
In that case - yes. You will have to fight (usually) 3, two with dual plasma rifles and one with sword, right after you do the first sniper part. (The one that comes right after the pelican part)
