 The precise role and contribution of war chariots in battlefield is a matter of dispute due to the lack of sufficient evidence . In general , it appears that during the first centuries ( 16th – 14th century BC ) chariots were used as a fighting vehicle while later in the 13th century BC their role was limited to a battlefield transport . Horse @-@ mounted warriors were also part of the Mycenaean armies , however their precise role isn 't clear due to lack of archaeological data .
