Headset plug adapter

[Esch]

This is probably a dumb question, but my search hasn't turned up very much.

I have an old DC military headset (H10-76) with a single plug, that I plan on using on an upcoming lesson. I sorta forgot that civilian aircraft use the dual-plug system, been a while. What type of adapter or other changes (microphone, maybe) would be necessary to convert my headset for civilian use?
