No convection path for resistors, obstructed by boards.
Its always something to keep in mind. The other thing is also to keep resistors spaced a few mm away from the board.

...unless you design for huge accelerations and vibrations. ;-)
Design of a stuff for military is quite tricky!

Hello ... because as the title says this is a gallery section just for a pictures and a few comments etc
But we have (not this one) endless examples of people entering comments that have nothing to do with the original post.
Then we have post after post with numerous threads. .at this point the gallery section stops becoming a gallery section.
In this instance I agree with the moderators, a few comments is fine in my opinion
