When Rose is introduced to the entire team McGloin shakes her hand and says that he (respects or admires) anyone that has survived the POW school. She smiles, nods and walks away. McGloin then explains to the last remaining teammate that all NIOs attend the POW school and explains briefly what it is. First: It is the SERE school. Survival, Evasion, Resistance and Escape not really POW. Second: Not all, not even most, NIOs attend SERE school, just some.
