What METT-TC factor is at the root of the questions. Do I remember the training I received about what to do when encountering unexploded ordinance?

The METT-TC factor at the root of this question is "Terrain and Weather," specifically focusing on the terrain aspect where unexploded ordnance (UXO) may be encountered. The effectiveness of training is often influenced by the operational environment and conditions. Ensuring that personnel remember their training in such situations is crucial for safety and efficacy in response actions. Regular drills and refreshers can help reinforce this knowledge.
