Sorry if this one's been flagged before (I didn't search), but as of TMR version 0.3.4 I found an interesting situation while playing the PCML Guidance Scenario. If I throw my PCML on the ground and switch to my LMG, I can crouch and rest on the PCML... which is sort of fine, though the object looks a bit low to the ground for that to look like it should work. Where it goes odd is when I hit TAB to switch to hard rest, I can now aim all the way up to zenith of my view, turn 180 degrees, etc., and still not lose my hard resting status. I just now tried a few other scenarios and see that this works for other low-lying objects such as the weapons crate.
Edit: Actually, I don't even have to crouch. I can stand bolt-upright, look down at an object on the ground (PCML in this particular case), TAB to hard rest, and fire away with impunity in any direction.
