Which of the following is considered a common tactic used by saboteurs?

The use of chemical means is indeed a common tactic employed by saboteurs because it can create disruptions or damage without a direct confrontation. This method can involve the use of harmful substances to contaminate environments, destroy materials, or incapacitate operations within a facility. Chemical sabotage can have widespread implications, affecting not just the immediate target but potentially causing health risks to employees and the surrounding community as well.

In contexts of sabotage, chemical means often require a level of specialized knowledge, making it a calculated approach to creating chaos or hindrance. Saboteurs may use this tactic to target specific assets, disrupt production processes, or undermine public confidence in an organization.

While other tactics mentioned, such as organizational sabotage and political pressure, can effectively disrupt operations, they typically rely on more indirect forms of influence or manipulation. Protesting, while a form of expressing dissent, is generally more aligned with activism and does not carry the same intent of covertly undermining operations through physical or tactical means.
