I’m going to imagine OP’s parents are from a first world country and of good health, in that situation, you’re right.
There are programs in place though to make it easier for service members to emigrate family members and USCIS tends to approve expedite requests submitted by service members fairly quickly too, especially if there’s someone from your COC endorsing it, which is easy to do. I’ve met a lot of service members who have expedited family members with little to no effort under the estimated time needed. Happens a lot you just need to be in the military to see it (and in that circle). Your installation USCIS liaison will tell you this to your face (@OP) and they’re a better source than this forum tbh
