Final answer:
The student's question references Chapter 7 of TC 21-305-20, but the provided information about '7.17: Chapter 7 Attributions' by Deborah Gustlin & Zoe Gustlin does not correspond to a military manual. It indicates a probable misunderstanding or mismatch of the document's content.
Step-by-step explanation:
The student is asking about Chapter 7 of TC 21-305-20. However, the information provided seems to be incorrect or mismatched. The reference to 7.17: Chapter 7 Attributions by Deborah Gustlin & Zoe Gustlin is related to an open educational resource and does not appear to correlate with the military manual TC 21-305-20 which is a training circular for vehicle operations. Therefore, we may deduce that the student is actually inquiring about a different Chapter 7 or there might be confusion regarding the document title or content.
