Stealth refers to a method or technique used to avoid detection, often in military operations. It involves using strategies and technologies that help reduce visibility, noise, and other signs that might give away one's position or intentions. Stealth can be applied to various aspects of an operation, such as stealth technology on aircraft or ships, stealth tactics used by soldiers, or even stealth marketing techniques in business. The goal is always the same - to remain hidden and undetected until it is advantageous to reveal oneself.
