Final answer:
When Navy items are un-serviceable and need to be turned in to the DOP, there are specific identification methods used to ensure proper disposal and replacement.
Step-by-step explanation:
When Navy items are un-serviceable and need to be turned in to the DOP (Disposal Officer Program), there are several identification methods used. One common method is the tagging or marking of items as un-serviceable. This can be done by attaching a red tag or marking the items with red paint or tape. Another method is to place the items in a designated area or bin for turn-in to the DOP. These identification methods help ensure that un-serviceable Navy items are properly disposed of and replaced as needed.
