What are Man-Portable Air Defense Systems (MANPADS) primarily known for?

Man-Portable Air Defense Systems (MANPADS) are primarily known for being lethal, portable, and highly concealed. Their design allows individual soldiers to carry and deploy them easily, which enhances their effectiveness by enabling quick reactions in combat situations. The portability aspect means these systems can be maneuvered without the need for heavy transport vehicles, making them versatile on the battlefield. Additionally, they are often designed with features that allow for concealment, making it difficult for adversaries to detect them until it's too late, adding to their lethality.

The other choices describe characteristics that do not align with the nature of MANPADS. Large missile systems designed for strategic defense refer to heavier, more complex systems with significant infrastructure needs, while high cost and extensive requirements would not apply to the lightweight and relatively straightforward nature of MANPADS. Limited range and accuracy could also be attributes of certain air defense systems, but MANPADS specifically are valued for their operational effectiveness at short ranges against airborne threats.
