oh yes.
there are even feminist sahms who are nothing to do with the military y'know. 
it's more.... how you sahm.
and the beliefs you are passing on to your dcs etc. it would be a bit more problematic if you were teaching the girls to look nice, not get dirty, smile, and how to cook and iron, and one day they'll marry a rich chap, and getting the boys to be brave and not cry, because boys don't do that, and waiting on them hand foot and finger. (and of course how your model your relationship with dh... if like, a friend of mine, you greet him at the door with a g&t in a bikini every night, with dinner simmering on the stove - it might be more problematic)
but really, the understanding that (at least in the uk) society is very much set up for the woman to be the ft childcarer (in terms of parental leave and work practices etc - you only have to look at alan sugar's view on employing women of childbearing age...) flexible working deals, even pay for nursery workers or carers. there are of course sahds, but they are very much in the minority. it looks difficult to reconcile from a service pov, as there is more formal recognition that a woman plays second fiddle in terms of expectations to maintain the servicemans availability for work and deployment etc, but it's really very interesting.
i particularly like looking at the volunteer roles that wives take from a unit cohesion pov - and there's lots of us research on military spouses and employment (you can have a look at that wifey - try RAND, they have bags of it, all very depressing in terms of levels of employment and wage earning/ level capability, as well as educational attainment).
in fact, looking at it all from a feminist pov makes it all far more interesting. 
i'm actually toying with putting together a short research project looking at military spouses and feminism - as i said, it hasn't been done since yonks ago. but as dobroevsky (or whoever it was) found out, it's quite difficult, because military spouses automatically feel it doesn't apply. or think because they are trailing they have automatically flunked feminism 101, or whatever. so are reluctant to even consider their life through that lens...
anyway, i'm pondering. i was due to write a paper on support networks for military spouses in the next couple of months (formal and informal), but i'm wondering if a feminism angle might be more... interesting.
wanna do an interview?
