Eastern Communications Post was a Soviet outpost in Afghanistan. It was implied by Kazuhira Miller that this outpost was important for Soviet communications in the region and that destroying equipment there would put a hole in the Soviet base-to-base comms network.
In 1984, Venom Snake infiltrated the outpost and destroyed comms equipment there in an effort to prevent reinforcements being sent between outposts.
Behind the scenes
In Episode 1: Phantom Limbs, if the player heads over to the Eastern Communications Post instead of heading to Da Wialo Kallai, the player can find the intel file relating to Miller's transfer, with the scene and dialogue otherwise remaining the same as if the player found the intel file at Wialo village.
If the player manages to destroy the communications equipment in the Eastern Communications Outpost before starting Mission 4: C2W, Miller will give the briefing as usual, only for Ocelot to cut in and tell Miller that the equipment is already destroyed, even making sure to confirm that Snake had indeed destroyed all of the equipment, with Miller sheepishly congratulating Snake for completing the mission. It should be noted that if you do this method, you don't get a grade at the end of the mission. The method can only be accomplished if you start the mission while in free roam mode.
