1.0.7
June 7, 2026
v1.0.7 — Two new Fire Support Planning classes. The Planning pillar (unlocked at SSG with all four Advanced classes complete) now has four classes instead of two. P3 — EFSTs & THE SCHEME OF FIRES. The Essential Fire Support Task — what makes a fires task "essential," how TPME (Task / Purpose / Method / Effect) structures it, and how EFSTs sequence into a scheme of fires the FO executes. 6 lessons, 6 quiz items, 4 recall cards, 2 applies-or-not drills, and a chip composer drill where you assemble a complete EFST in TPME order. P4 — INTEGRATING FIRES WITH MANEUVER. Fires nested in the maneuver scheme. The four essential fires tasks (enable / isolate / screen / suppress). SOSRA — the deliberate breach sequence, all five letters: Suppress, Obscure, Secure, Reduce, Assault. The FO's critical lift/shift call during Assault. Trigger lines (phase / terrain / time / NAI). Phased fires across an operation (preparation / shaping / decisive / sustaining). Worked example: deliberate breach of a wire obstacle at a notional EE platoon position, walked through every SOSRA element with the FO's exact calls. 6 lessons, 7 quiz items, 4 recall cards, 2 applies drills, and a chip composer where you assemble SOSRA in doctrinal order. Both classes are FM 3-09 grounded with verbatim chapter / paragraph citations in the lesson text. Order-strict matching enforces TPME on P3's chip drill and S-O-S-R-A on P4's chip drill — answer out of order and you're wrong, just like the doctrine. Built by a 13F with 20 years AD. Standards-only — doctrine governs.
