Controlling an enemy's perception of the battlespace includes manipulating his view of the threat, his own troops and status, and the environment in which he operates. This will be accomplished by selectively denying knowledge to the enemy while presenting him with information that is either misleading or serves our purposes. Sensing and feedback of an enemy leadership's perception of the situation will be critical. Technologies of interest here include those that allow systems and entire force units to modify their signature from being very stealthy to being completely obvious. An ability to attack enemy information systems will also be critical, encompassing system technologies from laser-based counter sensor weapons to embedded computer viruses, commonly referred to as Trojan Horses. In all cases, the goal will be to deny the enemy any information that would be useful to him and to impose a construct of deception and misinformation at all levels of operations. Clearly, technologies necessary to achieve battlefield awareness already mentioned will be crucial in allowing a "perception attack" (a form of information warfare) to be successfully carried out. The need and requirements for Battlefield Damage Assessment (BDA) will increase dramatically. It will be necessary to understand not only whether a target was killed but also how enemy leadership, troops, and society viewed this destruction. So far, primarily information technologies have been discussed. Obviously, there will continue to be requirements for numerous other types of systems. Among the more important system technologies critical to achieving control of the environment include: - Weapons platforms with stealth technology - Weapons systems - Robotic systems Weapons platforms One of the fundamental rationales for weapons platforms is to move people and ordinance to within an effective range of the target. Centuries before smart weapons and robotic systems, this reasoning was understood intuitively. Since ordinance must still be placed on the target, weapons platforms such as described below still demand consideration. - Stealthy bombers and strike aircraft either land or sea platform based - Arsenal ships - Submarines with conventional cruise missiles - Stealthy land vehicles - Stealthy observation/attack helicopters Stealth, combined with stand off, will contribute strongly to the protection of manned systems on the modern battlefield and will also be used extensively for other, high-value unmanned systems. However, protection of the force is inherent within the concept of Rapid Dominance, and it will rely upon the control of information and the enemy's perception of events, stealth being one of the elements enabling this control.
