The Revolutionary Army is one of the biggest organizations that is currently functioning in the One Piece world. This organization is actually powerful enough to take on the entirety of the World Government and challenge the supremacy of the Celestial Dragons. That in itself is proof of how great this army truly is. The Revolutionary Army has always been somewhat of a mystery in One Piece and this is likely because of the fact that this organization would be the most relevant in the Final Saga of One Piece.
