Bad form, but I'm replying to my own message - 'cause I forgot to tie it into
Star Wars.
I did a quick study a couple of years ago on the AT-ST. If you check out the
pictures from the movie, you can see that the AT-ST does indeed have a knee
that faces the correct direction ... plus an ankle ... plus a toe joint ...
plus one extra one between the ankle and toe:

1 = thigh
knee joint
2 = shin
ankle joint
3 = foot section 1
new joint
4 = foot section 2
toe joint
5 = toe
The AT-AT also has this small, body-packed upper leg section. The legs of the
AT-AT actually attach to the body near the center, but there are small leg
sections, hidden behind the lifting brackets, that extend either forward or
backward. Attached to these are the long, vertical leg sections. In that
sense, the AT-AT *does* have backwards knees on the rear legs.
Anyway, just some points of interest.

| (...) Well, if this is indeed the case, then we should ask LEGO to give us a more accurate Special Edition AT-ST that has the correct working knee joints and such. Also, making octagonal pieces like in the side cannons in the picture that you posted (...) (22 years ago, 9-Jan-03, to lugnet.off-topic.fun)
