Jihad. A person who goes on jihad is a mujahid. However, the word actually means "struggle," and a generous interpretation defines holy war as "lesser jihad" and struggle within oneself as "greater jihad," so you can make the argument that simply saying jihad means holy war is oversimplistic. Those who identify themselves a mujahideen, however, are generally NOT claiming that they're engaged in rigorous self-examination.
