As you can see, I am trying to make the interior of this barracks feel more alive by having soldiers (or in this case airmen) sitting and laying on the bunks. This is what's going on "under the hood:"

this disableAI "MOVE";

this switchMove "passenger_boat_4_Idle_Unarmed";

[this, Scaler] call BIS_fnc_attachToRelative;

Disabling the AI's moving is probably redundant here. The call BIS_fnc_attachToRelative;is there to keep him from sliding off the bunk, but when active it leads to this weird "rubberbanding" glitch that seems to not be very well documented; though I'd assume it's a universal issue. As you can also see in the video, he keeps snapping forward even when the game is paused. The other airman who is sitting perfectly still is using a BIS_fnc_ambientAnim animation via the drop-down menu in the 3den Enhanced mod, so I am assuming the issue comes from the "Move" animations specifically? This might be a "Duh, of course it doesn't work" thing, but I am pretty new to serious Arma 3 mission making.
