Would a full body diamond armor and sword guarantee survival and victory against a medieval battalion?

Would modern age military skills be useful during the crusades?

No Modern soldiers are trained and equipped to modern warfare. They are next to useless for ancient warfare. At best, they wouldn't be better than any other piece-of-flesh to make for cannon-fodder ...
