As someone who owns exactly one suit, this topic may seem significantly outside of my wheelhouse.  And it is.

Rucking and load support in full kit is an activity that many Tactical Human Performance teams will help soldiers prepare for as part of their normal responsibilities.  The need for this may be due to preparation for selection, school, exercise, or deployment.
