v1.0.4 — FIST Cert Prep doctrine pass. Every Cert Prep question is now ATP-grounded: • 298 questions cross-checked against the source publications — ATP 3-09.30 Observed Fires, ATP 3-09.32 JFIRE, FM 3-09 Field Artillery Operations, JP 3-09 Joint Fire Support, JP 3-09.3 Close Air Support. • Every explainer carries a verbatim doctrine quote with chapter citation — no AI-paraphrased answers. • 57 wrong-answer corrections. Examples: "Fire support system" → "The Fires Cell" (ATP 3-09.30 1-3). "Tailoring" → "Task-organizing" (FM 3-09 4-33). "Survey" → "Mensuration" (3-6, citing JP 3-60). "17.78" → "17.8" (3-22). 120mm 4-tube FPF: 140m × 25m → 300m × 75m (Table 1-1). • Official JFS MQF test composition: SL1 test = 50 SL1 questions. SL2 test = 50 SL1 + 25 SL2 = 75 questions. SL3 test = 50 SL1 + 25 SL2 + 25 SL3 = 100 questions. Practice mode scales the same composition to 20. • 13 sequence-sensitive questions now enforce doctrinal order — the 15 subsequent corrections (ATP 3-09.30 5-24), SLOCTOP and FAPARCA memory aids, the 9-line CAS brief, CFF elements, methods of engagement, etc. • 35 questions whose answers couldn't be located in any available source publication were quarantined rather than served with guessed content. Coming back when the Nov 2023 ATP 3-09.32 is reachable. Built by a 13F with 20 years AD. Standards-only — doctrine governs. When the doctrine and the popular convention disagree, doctrine wins.

Version 1.0.3 is a polish-and-performance pass. FIXED — GETTING BACK TO THE MAIN MENU • You can now return to the Operations Board from every section — Basic Training, Fire Missions, ROC-V, and the FO tools. Previously a few screens had no back control and you had to close the app to get out. Every screen now has a clear back button. IMPROVED — CONSISTENT LOOK • The topographic brand background now runs consistently behind every screen, top to bottom — tools, classes, references, and more — for a cleaner, unified feel. IMPROVED — SMALLER, FASTER • ROC-V threat photos are dramatically more efficient — smaller app download and faster image loading. • General stability and polish. Thanks for training with Steel Rain. Keep the rounds on target.

Version 1.0.1 is a full quality pass on the app plus a new senior training track. If you trained on the first release, this is the version you want. NEW — FIRE SUPPORT PLANNING TRACK Go beyond calling individual missions and into planning and integrating fires. • D3A Targeting Cycle — Decide, Detect, Deliver, Assess, and exactly where the observer plugs into each phase, from detection to honest battle damage assessment. • High-Payoff Targets & the Attack Guidance Matrix — high-value vs. high-payoff targets, the high-payoff target list, target selection standards, and how to read an attack guidance matrix. • Unlocks as you rank up, so it's waiting once you've proven the fundamentals. FIXES & IMPROVEMENTS • Bootcamp content — reviewed and corrected lesson content and answer logic across the classes; fixed bad prompts, unclear steps, and grading edge cases. • Call for Fire input (iOS) — the keyboard now has a clear DONE / SEND bar, so your mission always sends cleanly instead of getting trapped behind the keyboard. • Stability — numerous reliability fixes so sessions don't stall or drop progress. • Accuracy — drill corrections so what you're taught lines up with doctrine. • Progression — rank and unlock flow cleaned up so finishing classes advances you correctly, all the way to the new senior track. Thanks for training with Steel Rain. Keep the rounds on target.
