Final answer:
The relationship between soldiers and priests in missions was complex, marked by occasional conflicts due to differing goals. The Reconquista was indeed a military and religious effort by Christian Spaniards, and recruiting native allies was crucial in the Spanish conquest of the Aztec empire.
Step-by-step explanation:
The student's question about whether soldiers often did not get along with priests in missions is reflective of a complex historical relationship that varied largely depending on time and location. However, there are historical examples from the Spanish colonial period where tension between military and religious figures did occur, as they had differing objectives and methods for mission administration and native interactions.
In reference to the other provided statements, reconquering the Iberian Peninsula, known as the Reconquista, was indeed both a military and religious action. It was a long-term effort by Christian states to reclaim territory taken by Muslims (Moors). The claim that many women found themselves incapable of handling the burdens of war is a generalization that may not be entirely accurate, as there are also many historical instances of women taking on significant roles during war times when men were absent. Also, recruiting native allies was critical in the Spanish conquest of the Aztec. In fact, without the support of certain indigenous groups, the Spanish would have had much more difficulty achieving their conquest.
