Unlike the Spartan-IIs, the IIIs didn't have any combat experience before fighting the Covenant. The IIs fought for years against the Insurrectionists, who were very crafty and devious (remember the truck-tyre bombs from Contact Harvest?). That's one of the things that made Chief and the other IIs so deadly: they were just as cunning and they did crazy stuff. Instead of going through the station to the Pelican's docking bay, Jorge just floated over nonchalantly, probably the only daredevil moment in the whole game. The IIIs act more like ODSTs with awesome armour.
Sure, the slipspace bomb was a daring idea, but Kat just copied an earlier accident. When Chief jumped out of Cairo station, did he say that he read about this in a mission report? Nope. . .
