E4 or something fun?

I’m 28, married, a homeowner, and a father. I’m looking to fulfill a long-time goal of serving in the military. Active duty isn’t an option for me, so I’m deciding between the Reserves and the National Guard (Massachusetts or New Hampshire).

I’m currently a truck driver with a Class A CDL, including tanker and doubles/triples endorsements, and I have close to seven years of experience. I’ve been considering joining a transportation unit in the Reserves, potentially through ACASP as an 88M, which would allow me to start as an E-4 and possibly shorten AIT. I’ve also looked into joining a Forward Support Company (FSC) in the National Guard as an 88M.

At the same time, I think I might really enjoy something like 12B (Combat Engineer) or another more hands-on MOS that would make drill weekends more engaging. My concern is ending up in a Reserve unit that feels slow-paced, with limited opportunities for deployments or meaningful training.

Would it be better to pursue ACASP as an 88M in the Reserves and volunteer for deployments when possible, or join the National Guard—either as an 88M for the rank benefits or in a more hands-on role like 12B for a more engaging experience?

Thanks in advance
