In the Bronze Age, was it preferable to capture and ransom charioteers?

Here’s Anthony Spalinger talking about the campaigns of Amunhotep II (War in ancient Egypt, 2005, pp. 140-141):

During his Syrian expedition some maryannu warriors were captured as well as horses and chariots. Protective armor, quivers, and bows were also recovered from the defeated enemy. … The war booty is more useful to analyze as it provides some useful quantitative data. Five hundred and fifty maryannu were taken … It is probable that the men were brought back to Egypt as future soldiers because 240 of their wives are also listed. … Six hundred and forty Canaanites are also recorded, and here we cannot but conclude that the Pharaoh had to take care of some rebels in Palestine. Connected to the last are 232 of the children of the princes and 323 of their wives. Two hundred and seventy female singers are included, who brought along their musical implements. The second campaign of Amunhotep in year nine was more limited. … The area was on the border of Egypt’s control in the central por­tions of north Palestine. … From this region the king obtained 34 princes, 57 maryannu, and 231 living Asiatics.
