A listening post
The South Korean Listening Posts are destructible objects found in the world of Mercenaries: Playground of Destruction.
Description
Northern Listening Post.
These metal poles sit on a four-legged base, with the pole rising up to ten feet. At the top of the post are two dishes, one pointing one way, and the other pointing in the opposite direction. The receiving antenna inside the dishes blinks red, which reflects off the dishes.
The Listening Posts themselves are extremely easy to destroy, and are quite vulnerable to small-arms fire; however, it is advised not to stand too close because the explosion will harm anyone who is too close to it.

Southern Listening Post.
The South Korean government placed these Listening Posts throughout North Korea, as well as a small portion of China (in the northern province). They're aimed at intercepting Chinese plans for attacks on the South Koreans due to them having the same goal during the Song Initiative.
Listening posts can also be found in areas that are under the control of the AN and Russian Mafia, however, these are to a lesser extent due to those two factions not being direct enemies with the South Koreans. The Chinese will pay the mercenary $5,000 for each one detsroyed and destroying them will also increase their favour towards you.
