Soldier Protection System (SPS)
Print Friendly, PDF & Email


The Soldier Protection System (SPS) is the Army’s next-generation Personal Protective Equipment (PPE) system. SPS is a modular, scalable, tailorable system designed to defeat current threats at a reduced weight in comparison to the Army’s existing PPE. The SPS is based on the parallel development of five subsystems.

The Vital Torso Protection (VTP) variants include lighter weight Enhanced Small Arm Protective Inserts/Enhanced Side Ballistic Inserts (ESAPI/ESBI), as well as the X Threat Small Arms Protective Inserts (XSAPI) and X Threat Side Ballistic Inserts (XSBI) for deployers.

The Torso and Extremity Protection (TEP) is further comprised of multiple components, including the Modular Scalable Vest (MSV), the Ballistic Combat Shirt (BCS), the Blast Pelvic Protector (BPP) and Ballistic Battle Belt (B3).

The Integrated Head Protection System (IHPS) will include a 5 percent lighter weight helmet system composed of helmet/maxillofacial and passive hearing protection with increased blunt impact performance.

The Transition Combat Eye Protection (TCEP) will include ballistic protective eyewear capable of transitioning from light to dark and dark to light in less than one second, providing a 10 percent increase in fragmentation. This capability aids Soldiers in a combat environment to move rapidly in varying light conditions.


SPS increases the warfighter’s lethality, mobility and modularity by optimizing Soldier protection while effectively reducing weight with the latest technologies and managing all life cycle aspects of personal protective equipment. SPS replaces the capability of multiple current systems to provide the Soldier with an overall 10 percent weight reduction. SPS provides the Soldier with multiple levels of ballistic protection tailorable to a broad range of missions. This modular, scalable approach increases Soldier survivability and mobility and contributes to increased force protection.


VTP achieves 7-14 percent weight reduction over the current plates

  • ESAPI and XSAPI sizes: XS, S, S-Long, M, L and XL. Two additional sizes are in development XS-Short and S-Short to accommodate smaller-statured Soldiers.
  • ESBI and XSBI sizes: Small 6×6 inches, Medium 6×8 inches and Large 7×8 inches
  • Weight (Medium size): ESAPI = 5 pounds (7 percent reduction); ESBI = 1.99 pounds (9 percent reduction); XSAPI = 5.5 pounds (7 percent reduction); XSBI = 2.20 pounds (14 percent reduction)

TEP achieves 18.98 percent weight reduction over current soft armor vest/plate carrier

  • Number of sizes: MSV= 8; BCS = 10; BPP = 6; B3 = 3
  • Weight (Medium size): MSV GEN II = 7.6 pounds; BCS = 2.95 pounds; BPP = 1.6 pounds; B3 = 1.7 pounds

IHPS provides Soldiers Threat M protection and, with a ballistic applique, has the capability to adapt to Threat P rifle protection, the most prevalent threat in theater. Each of the IHPS components has a separate purchase description: Modular Helmet, Ballistic Appliqué Visor, Mandible, Helmet Cover and Retention System
