The USGI EE8 Field Phone is an authentic EE8 field phone that was the standard issue field phone for the US Army from World War II through Vietnam. Soldiers in the field would string communications wire between two locations and then use the EE8 to establish secure and reliable communications between two locations. Field phones were used to ensure the enemy was not able to listen to communications between field teams. By using wired communications no outside party could listen into communications, making field phones a secure communications method for soldiers in the field.
