From FM 4-20.147: Airdrop of Supplies and Equipment: Humanitarian Airdrop
> EXTENDED TRI-WALL AERIAL DELIVERY SYSTEM (TRIADS). The TRIADS system is a corrugated tri-wall box rigged for static line deployment off the ramp of an aircraft using CDS procedures. Typical loads include loose Meals Ready-to-Eat (MREs) or Humanitarian Daily Rations (HDRs). Following deployment the caps of the box separate from the sleeve allowing the container’s content to scatter and freefall to the ground. TRIADS has a 1,375 pound load capacity.
Did the military drop it without parachutes? Almost certainly. It's a standard method with standard procedures to follow.
Was it destroyed on impact? Probably not. A certain amount of breakage can be expected, from containers that fail to open properly, or from supplies that land badly. If all the intact supplies have been removed, it would give the impression that everything was destroyed on impact.
