The four commanders of Hizbullah

Saudi media is as funny about Hizbullah as Western media.  According to Saudi and Hariri media, Hizbullah only has four commanders/fighters and it uses them in all military missions: the same four people are named for murder of Hariri, murder of Hasan, the bombing in Bulgaria, and now leading the fight in Qusayr.  Hizbullah does not have other members.fighters it seems.
