In the beginning of "Avengers: Infinity War", Thanos and the Hulk had a very intense fight:
While the Hulk fights like he's brawling in the street, Thanos is more composed and posing in stances like in most martial arts, so he seems to be using a specific fighting technique. Moreover, his style looks like something between boxing and/or krav maga, but the fight ends quickly so unfortunately we only see a few of Thanos' moves, as
he easily beats the crap out of the Hulk.
So my question is: What is exactly Thanos' fighting technique?
In-Universe info would be preferable, but out-of-Universe would be also ok if the former is not available.
