What is encompassed within Counterreconnaissance?

Counterreconnaissance involves measures taken to counter enemy surveillance efforts. This focuses on ensuring that one's own forces are not easily identified or targeted by opposing reconnaissance units. Effective counterreconnaissance includes various tactics and strategies designed to obscure personnel movements, mislead enemy observations, and reduce the likelihood of detection.

In contrast, direct combat with enemy units centers around active engagement and confrontation on the battlefield, which is more aligned with offensive operations rather than counterintelligence. Creating supply strategies pertains to logistics and resource management, important for sustaining operations but not directly related to reconnaissance countermeasures. Evasion tactics for troops may help in avoiding detection, but they fall more into the category of operational security rather than a systematic approach to countering enemy surveillance. Thus, focusing specifically on measures to thwart enemy reconnaissance makes the second choice the appropriate answer.
