Phalanx The close order of battle in which the heavy-armed troops of a Grecian army were usually
drawn up. Hence, any number of people distinguished for firmness and solidity of union.

I have read that Philip of Macedon devised special tactic of equipping phalanx with extra
length heavy spears, so that when they charged enemy with only shields and swords
could not withstand their charge.

Anatomy: bones beneath palm, between wrist and fingers. Pl. phalanges.
