Some of the assets located in the Laotian jungle have not been specifically built and are either partially natural or otherwise hidden as part of the jungle. These assets are some of the most dangerous as they can be difficult to spot or can prove dangerous under the right circumstances.
Un-eXploded Ordinance, in-game refers to old unexploded Mark 83 1,000 lb. bombs dropped by American B-52's during covert bombing operations against VC positions in Laos. Some of these old bombs have not detonated upon impact and have remained on the ground. They are fairly stable but can detonate if disturbed by other explosions so it is advised to not get into trouble when one of these is nearby. UXO's can be searched for intel and can be detonated with the help of a C4 charge, 40MM grenade, M72 LAW rocket or support in order to deny the enemy of possible construction materials for IED's (Improvised Explosive Devices). It is inadvisable to detonate it with grenades as the throwing range is often too short to escape the blast radius. UXO's can also be photographed for a camera bonus in the form of BDA, or Battle Damage Assessment, information.
The VC forces run regular patrols in parts of the border region. These high-activity routes quickly become easily visible in the environment by a set of footprints, and are a sign for the commander that the area is a hotspot for enemy forces. Tracks are excellent positions in order to either set up a trap or to simply observe the hostiles for high intel quantities. Camouflage is important as the hostile patrols move in very wide areas along the trail in the direction specified by the footprints and being spotted by up to a dozen hostiles is never healthy.
Traps are an old but effective way of slowing down hostile forces, and the VC guerrillas are masters of such tactics. If the commander gains heat, traps begin to appear and are one of the first signs of the the enemy's awareness of LRRP activity. Their numbers quickly explode as the heat goes up. Traps are extremely dangerous for the Rangers due to their high lethality and difficulty to spot in time. If traps have begun to appear, it is important to move slowly and scan the environment before moving forward in order to avoid them. Once spotted, a trap is effectively neutralized and will not cause any harm even if walked over. Traps can also be photographed for intel.
Traps include punji stick traps, landmines, pressure plate mines and flare mines. Punji stick traps generally cause minor injuries, while landmines can potentially wipe out an entire Ranger team. Pressure plate mines do not detonate when a Ranger steps on it, but rather when a Ranger releases the pressure by moving off the mine. The Ranger that steps on it will stop and the mine has 3 chances to be diffused, depending on the demo skill of the Ranger selected to diffuse it. A flare mine does not cause damage but it alerts the enemy and gathers all available VC troops to the location of the trap, potentially swarming the Rangers.
These sites show the more gruesome side of warfare (war is gruesome enough as it is), either remains of the casualties of the First Indochina War, a large scale execution, or burial sites of the victims of US bombings. While possibly even 30 years old, these areas still can provide some information about the local hostiles. Searching these can potentially yield hard intel if the commander chooses to disturb the dead and they can also be photographed for intel.
These are small areas filled with various pieces of trash and garbage left behind by groups of VC fighters in the area. Skilled Rangers can search the pile in order to find information about the enemy among the debris, and can also be photographed for intel.
