what i mean is, they are allowed to recourse the basic
qualification courses three times.
meaning, if they get pregnant during BMT, they can give birth and
return to BMT after.
as for vocation change, it usually happens to courses where you
will need to pass to get the vocation you sign on.
eg, a lady signs on as guardswoman, she will need to pass GCC. If
she fails 3 times (or more by discretion), she will need to
re-vocate to infantry or she will be stuck in rank.
anyway, this is what i was explained by a servicewoman... so i
dunno how the actual contract says.
