I want to know the answer to the following question:
Philip II used a dense military formation called what?
All the background I'm provided with is that "Hellenistic warfare was a continuation of the military developments of Iphicrates and Philip II of Macedon, particularly his use of the Macedonian Phalanx, a dense formation of pikemen, in conjunction with heavy companion cavalry.". Is that enough to answer the question?
Answer: yes
