AR 34-1 defines interoperability, establishes four interoperability levels, and identifies priority functional areas including information systems, intelligence, fires, and sustainment. It addresses Army participation in multinational interoperability forums, development of agreements and publications, and assessment of interoperability outcomes.
Interoperability must be routinely considered and supported as part of Army planning, programming, budgeting, and execution (PPBE); force design; force structure; doctrine and policy; training; weapon systems and materiel requirements; research, development, and acquisition; information and data processes for assessment, monitoring, and evaluation (AME); materiel management; and logistics support processes. (paragraph 7)
The order of priority for achieving interoperability will be internal Army (multi-component), Joint, Inter-organizational and MN. The Army will address these priority areas simultaneouslynot sequentially. (paragraph 7)
The Armys interoperability PFAs comprise the following functional areas: communication and information systems (CIS)/information management (IM); intelligence, surveillance and reconnaissance (ISR) and intelligence fusion; digital fires; and sustainment. (paragraph 1-9)
To standardize interoperability planning, the Army recognizes four levels of interoperability with UAP: Level 0 (Not Interoperable), Level 1 (Deconflicted), Level 2 (Compatible), and Level 3 (Integrated). (paragraph 1-9)
Requires alignment of capabilities and procedures to establish operational norms, enabling UAPs and the U.S. Army to complement each others operations. (paragraph 1-9)
