I have checked the meaning of "feature" in dictionary, and I could not decide which one fits the context. And what bothers me most is the verb used in the sentence, as in "tearing the security features apart", which makes "features" represent something solid, concrete and tangible. I guessed it should be a security equipment which could be torn apart, but no such definition in the dictionary.
Could someone help me to understand it?
Here is the sentence in the context:
Downstairs, Coulson heard the alarm. Perimeter breach. Attackers are wearing S.H.I.E.L.D. gear. He got to a secret locker and pressed his thumb against the security pad. Before it could open, the Hulk and Thor exploded up through the floor, tearing the security features apart.
So much for containment, Coulson thought.
“We have the Hulk and Thor on Level Four,” he said. “Levels Two and Three are dark.”
Maria Hill knew that if something didn’t distract the Hulk, he would tear the Helicarrier apart . . . which was, of course, exactly what Loki wanted. “Escort six-o,” she said. “Engage the big man. Get his attention. Don’t get too close.”
“Copy that,” came the pilot’s voice.
