Can you help me about the words in bold in the following passage?

There, the spectrum of emotions among service chiefs ran from sobbing to locker room raving.

I should add that the service chiefs of army were deeply disappointed and worried because the King, in fact their head, was leaving the coutry and they were watching him on TV.

Thanks a million.

Can you help me about the words in bold in the following passage?

The parting was emotionally charged. The Shah lost his composure, tears briefly welling in his eyes, when an officer of the Imperial Guard fell on his feet, imploring him not to leave. The scene, captured on cameras, became emblematic of an era about to end. At Supreme Command Headquarters in Lavizan, the spectrum of emotions among service chiefs ran from sobbing to locker room raving. As they watched the takeoff on television screen, one officer lay his head on Huyser’s shoulder and wept.
