As reported by AMSA:

On April 13, US TRANSCOM issued an update acknowledging that the Stop Movement Order created a significant operational and administrative burden for TSPs.

USTRANSCOM has approved a 10% adjustment to shipments processed during the Stop Movement Order timeframe.

This adjustment applies to shipments that were previously awarded to a TSP but cancelled or otherwise withdrawn from the TSP before the shipment was serviced as a result of implementing the Stop Movement Order. This adjustment also applies to all shipments awarded to a TSP during the Stop Movement Order period and serviced by that TSP. This adjustment does not apply to local moves, Non-Temporary Storage-Retrograde shipments, Direct Procurement Method and One-Time Only shipments.
