The 5.56mm SRTA provides a realistic restricted range training alternative to M193/M855 service rounds. The 5.56mm SRTA has a maximum range of 250 meters; an effective range of 25 meters (trajectory match and round to round dispersion comparable to the service ammunition) and provides a functional capability when used in the M16A2 Rifle with the M2 Training Bolt.

The Army continues to support the realization of low-cost, efficient training that provides a capability (5.56mm through Cal .50) to significantly enhance unit proficiencies in the small arms arena. Using the appropriate combination of NDI assessment, and developmental opportunities, small caliber training ammunition programs/acquisitions are in-step with the Army?s needs to train better and smarter. The generic use of Performance Specification Acquisition strategies have, in most cases, resulted in lower unit costs compared to the corresponding combat rounds. There are, however, additional operational and support cost savings and training enhancements realized by the short and limited range capabilities of these cartridges. Units are now able to train at nearby locations, accruing savings in terms of fuel, troop support, and billeting while increasing the opportunity to train effectively.
