nereas:I have often wondered why people join the Army or Marines when instead they could have joined the Coast Guard, Air Force, or Navy?
I think the reason is because daddy or grandpa was in the Army or Marines?
Or else they were in the Scouts, and that is more like the Army or Marines?
In terms of living a safe life with a long career, the Coast Guard, Air Force, or Navy are orders of magnitude above the Army or Marines.
In terms of better treatment and better duty stations, the Coast Guard, Air Force, or Navy are much more palatable than the Army or Marines. In any of these services there will be the hardship of separation from family and home. However overall the conditions are so much better in the Coast Guard, Air Force, or Navy than with the Army or Marines.
Maybe the difference is image?
I have no idea.
We joined the Army or Marine Corps. so people who did not have the intestinal fortitude didn't have to get drafted.
