Final answer:
AER, or Army Emergency Relief, provides financial support to soldiers and their dependents in times of emergency. Contributions to AER are voluntary and not a prerequisite for receiving aid.
Step-by-step explanation:
The purpose of AER, which stands for Army Emergency Relief, is to provide financial assistance to soldiers and their dependents. AER offers interest-free loans, grants, or a combination of both to help Army families with various emergency financial needs. For example, AER can assist with unexpected medical expenses, emergency travel, food, rent, or utilities. Contributing to AER is not a requirement to receive help. The assistance is provided based on need, not on whether the individual has contributed to the fund.
