Should I Leave a $79K Army Internship for Real Cybersecurity Experience?

A 23-year-old cybersecurity intern in the army, earning $79K, is wondering if he should leave his current position, where he has few technical tasks, to join another department where he would gain more practical experience but with a potentially reduced salary of $65K, no support, and a high-pressure environment. He holds a Sec+ certification and is considering preparing for the CISSP (Associate of ISC2) in his free time. He is torn between staying in his current position or gaining real cybersecurity experience.
