string theory - M branes/D branes are solitons?


I'm really confused.


In M theory/String theory, the fundamental objects are M/D branes. However, branes by defintion are just solitons. Solitons are just waves that maintain there shape.


So if a brane is a soliton wave, then what is it a wave of? Would it be the excitation of a field?
