Found an old folder of my Army records - which included copies of my pay records.
Before being sent to Vietnam my wife and I (because, as a dependent - she was figured into my wage)
You're paid by rank, and years holding that rank...and maybe "time in service".
As an E-4 (enlisted, 4 up from the bottom)
I received $369.35 a month, which included "dependent" allotment $90 to keep the wife alive for a month)
I was promoted quickly in Vietnam to E-5, (a $19 pay raise) ...and the Army added $16 for "foreign service", $65 for "hostile fire pay", and wife's allotment went up some, but since I was back living with the Army - the subsistance allowance fell away.. War zone service is tax free. So - was paid $463.45.
I was paid $36 in military payment certificates (MPC's) and had the remainder sent to my wife.
MPC's were changed frequently to defeat black marketing and drug dealers. (at the exchange table - "you don't get paid this much. Where'd it come from?")
My old Black 1st Sgt. said to me one time, as he watched the sun setting, "Well Doc, there goes another Buck.85 into the bank."
That wasn't much of an exaggeration.
Well, as they say - we weren't in it for the money😊
