## What is Steel Rain Call for Fire?

Steel Rain is a Forward Observer training app for 13F (US Army) and 0861 (USMC) MOS soldiers, FOs, FSOs, JFOs, ROTC cadets, OCS candidates, FA OBC students, and anyone preparing for NCO/officer boards, the FIST certification, or company-level fire-support positions.

WHAT YOU GET

• BASIC TRAINING — Nine interactive classes covering Call-for-Fire format, mils & direction, map reading, OT-line corrections, the 15 subsequent corrections in doctrinal order, mil-relation range estimation, FO loadout, and fire support products. Each class follows a four-phase pattern: lessons → quiz → drills → complete. Per-attempt option shuffle. Earn XP and promote.

• FIRE MISSIONS — Live adjust-fire and grid-mission scenarios. Transmit calls for fire by voice using on-device speech recognition. Walk rounds in. FDC TTS voices respond in real time.

• ROC-V THREAT RECOGNITION — Identify 25 near-peer combat vehicles from silhouette: Russian armor (T-72, T-90, BMP-3, BTR-82), PLA platforms (Type-99, Type-96, ZBD-04, ZBL-08, HQ-9), Iranian variants (Karrar, Boragh, Fajr-5), and globally-fielded UAS (Shahed, Lancet, CH-4, Orlan-10). Practice mode for studying. Test mode for +50 XP per category passed.

• ADVANCED PILLAR — SGT-locked classes for senior FOs and promotion study: Immediate Suppression, Final Protective Fires (plan/register/call lifecycle), Danger Close + RED (the 600m working rule), and CAS 9-Line with Type 1/2/3 control and cleared-hot procedures.

• FIRE SUPPORT PLANNING PILLAR — SSG-locked, opens after all four Advanced classes. The senior planning curriculum: P1 D3A Targeting Cycle (Decide / Detect / Deliver / Assess and where the FO plugs in). P2 High-Payoff Targets & the AGM (HVT vs HPT, the HPTL, TSS, and reading the Attack Guidance Matrix). P3 EFSTs & the Scheme of Fires (the Essential Fire Support Task — TPME, task & purpose, method & effects, sequencing into a scheme of fires). P4 Integrating Fires with Maneuver (fires nested in the maneuver scheme — SOSRA breach fundamentals, trigger lines, phased fires, and a worked deliberate-breach example with the FO's exact lift/shift call).

• FIST CERT PREP — 298 ATP-grounded MQF questions for the Joint Fire Support Mandatory Qualification File. Every answer 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) with the verbatim doctrine reference in every explainer. Official MQF test composition: SL1 = 50 SL1 questions, SL2 = 50 SL1 + 25 SL2, SL3 = 50 SL1 + 25 SL2 + 25 SL3. Practice mode, mock test mode, missed-question spaced repetition, and flashcards.

DOCTRINE GROUNDING

All content cites US Army FM 3-09 / ATP 3-09.30 / ATP 3-09.32 (JFIRE) / TC 3-09.8 and USMC MCRP 3-31.6, plus JP 3-09 and JP 3-09.3 for joint fires. Standards-only — no unit SOP. Target numbers use the AB#### format soldiers actually transmit. Target groups use A#A. The 15 subsequent corrections are sequenced per ATP 3-09.30. The Fire Support Planning pillar grounds in FM 3-09 with verbatim chapter and paragraph citations in the lesson text.

BUILT BY AN SME

Steel Rain is built by a 13F with 20 years active-duty experience. Every lesson, quiz question, and drill scenario has been reviewed against doctrine. When the doctrine and the popular convention disagree, doctrine wins.

NOT A GAME

Steel Rain is a training aid. Ammunition, range, and dispersion values are unclassified doctrinal approximations. Not for operational targeting.

NO ADS. NO TRACKERS. NO ACCOUNTS REQUIRED.

### 5/5 — SR NCO here

*2026-06-08*

Over all honestly not bad at all, it has all you need and it seems to be updating as long as it keeps docturnially correct, it’s solid, has the MQF for the job, roc-v which looked updated. Like it’s a good app, classes are good and even tests after as well. I definitely approve of this for training.

**Developer response:** Thank you, I’ve been updating right along with any bugs found. New things are coming soon along with more features and classes, appreciate the feedback

## Version history (last 5 releases)

### 1.0.7 — 2026-06-07

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.

### 1.0.6 — 2026-06-07

v1.0.6 — Direct-to-server bug reporting.

We were losing TestFlight feedback screenshots to Apple's delivery delays and to iPhones that didn't have Mail configured. v1.0.6 routes Report a Problem straight to our own server instead of through mailto: / TestFlight.

WHAT CHANGED:

• Settings → Report a Problem opens a proper sheet — type what happened, attach a screenshot from your camera roll (iOS screenshot: volume+power), toggle whether to include the local diagnostic log, hit SEND.

• Sent reports get a confirmation Alert ("Sent. Report received.") so you know it landed. No more wondering if the email actually went through.

• If you tap SEND while offline, the report is queued to SQLite and retries on the next launch with a connection. Up to 5 retries before it gives up.

• Every submission is gated on a verified bearer token, capped at 4MB per screenshot, and validated server-side before it ever touches the inbox.

WHY:

The prior mailto: flow depended on the tester having a working Mail app + Apple's TestFlight pipeline doing its job. We had a 4-day silence in mid-cycle where neither delivered. This bypass eliminates both points of failure.

Built by a 13F with 20 years AD. Standards-only — doctrine governs.

### 1.0.5 — 2026-06-06

v1.0.5 — Two fixes from SME field testing of v1.0.4.

1. PROGRESSION PERSISTENCE — XP, rank, and consecutive-days streak no longer reset on app update. A v1.0.4 user reported their PFC/SPC/SGT progression and streak disappearing after the TestFlight update. Root cause was a SQLite load failure being silently swallowed and overwritten by the next mutation. Fixed by:
  • Distinguishing "first install" (safe to initialize) from "load failed" (don't overwrite real data).
  • Adding a backup row that rotates on every save — load tries primary, falls back to backup on parse error.
  • Gating all mutator writes on hydrationSucceeded so a transient SQLite hiccup at startup can't clobber existing progress.
  • Surfacing all persistence errors via Settings → Report a Problem so we see future incidents.

2. FIRE MISSIONS — CFF INPUT NO LONGER COVERS THE MAP — The text input on iOS now stays compact (one-line minimum, three-line max) so the mission map remains visible while you type a call for fire. The huge multi-paragraph placeholder that used to inflate the input is now behind a "?" reference button — tap it only when you want the doctrine cheatsheet (Polar / Grid / Shift / FFE / IS / FPF / linear / munitions examples).

Built by a 13F with 20 years AD. Standards-only — doctrine governs.

### 1.0.4 — 2026-06-04

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.

### 1.0.3 (27) — 2026-06-04

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.
