The plan was for a concentrated attack against the Serbian army across the Vardar plain to neutralize it and to capture northern Macedonia, together with a less concentrated one against the Greek army near Thessaloniki, which had approximately half the size of the Serbian army, in order to capture the city and south Macedonia.
Plaan oli koondrünnak üle Vardari tasandiku Serbia armee vastu selle neutraliseerimiseks ja Põhja-Makedoonia vallutamine, koos vähem koondatud rünnakuga Thessaloníki juures Kreeka armee vastu, mis oli suuruselt ligikaudu pool Serbia armeest, eesmärgiga vallutada linn ja Lõuna-Makedoonia.
