The development of precision munitions and drones in modern warfare and the potential to change the rules of warfare with advances in electronic technology. In particular, in a defensive warfare scenario, the defender has a greater terrain advantage, allowing precision munitions to maximize their effectiveness and offset the numerical superiority of the enemy at a lower cost, maximizing the defensive success. Precision-guided munitions and unmanned aerial vehicles, in terms of technical characteristics and technological relevance can be said to be highly relevant. In the Second World War, Germany launched the Hs-239 remote control glide bombs and the U.S. Army VB-guided bombs; both were accurate munitions with the common features of unmanned aircraft. This type of equipment introduced in the 1940s, using the bomber projection and then the radio wave remote guidance method to combat long-range targets, remote control flight bombs with the appearance of small aircraft, can be regarded as the originator in the broad sense of unmanned participation in the war.

Precision munitions, as defined by the U.S. Department of Defense, are "a guided weapon designed to destroy a point target with minimal collateral damage, and can be air- and surface-launched missiles, multiple rockets and guided bombs.

In fact, these technologies can also be used in the control of drones. Unmanned aircraft are not new on the battlefield. The Royal Air Force developed the first drone in 1917; the United States also developed drones during the same period of 1916-1917, called the Hewitt-Sperry "automatic airplane," which is even considered the prototype of cruise missiles, once again illustrating the blood relationship between drones and precision-guided munitions.

With the development of technology in the 21st century, Taiwan's current drone and precision ammunition industry is quite limited, but the production chain of related technologies and systems is relatively complete, only lacking effective system integration. Therefore, if the R&D and production of information, communication, and micro-electro-mechanics can be effectively integrated, Taiwan will be able to quickly develop precision munitions and drone systems to meet the needs of defense.
