The text plays on the reinterpretation of a situation. Being 'surrounded' typically has a negative connotation, implying being trapped or in danger. However, 'a target-rich environment' reframes the situation into a positive one, suggesting there are many opportunities to engage. While this is a clever use of language, it does not involve a play on different meanings of the same word or similar-sounding words.
We aren ' t surrounded . We ' re in a target - rich environment .
