This is Thanos and CIS is on. If Thanos were faced with this many Hulks he would A) teleport himself from the battle, or if he had to fight for whatever reason B)BFR the Hulks into space where he could pick them off at his leisure (or alternatively, destroy the planet, but that would be a less desirable option, since it would provide the surviving Hulks with ammo to toss at him).
That's the only way Thanos takes it and he's smart/ruthless enough to do it. If BFR and running are eliminated as options, the Hulks take the majority.
