INTRODUCTION
An integrated theater area communications system must be established from division and corps
through echelons above corps (EAC) to allow the commander to command and control his
forces. The fielding of Mobile Subscriber Equipment (MSE) at corps and division has alleviated
many of the interface requirements at echelons corps and below (ECB) due to the commonality
of systems. However, tri-service tactical communications (TRITAC) systems constitute the
primary communications system at EAC. You, as the signal officer, must know how to interface
the two systems to have an integrated theater communications system.
