For first salvo in PP1 - the station (3-7) choose automatically consistently, JDAM STA3 - go to target 1, JDAM STA7 - go to target 2, according coordinates
For second salvo in PP2 - not choose automatically and both JDAMs (STA3 & STA7) go to same target... 3 or 4, according coordinates PP2 STA3 (or PP2 STA7)
