Syncing animation between 2 characters?

hello sorry if this has been asked before i couldnt find any similar questions. im doing a small project for college and i ran into a small issue. with this project the character has to get from a to b without being killed by the enemy. so all other animation is finished except for the hand to hand combat part. and was just wondering what methods are there for syncing the 2 animations together?. if i animated both of them in one scene in 3ds max (thats what i am using) it wouldn’t work. thank you for your answers
