Every entry on DA Form 5605-1-R exists because a record system needs it in writing. The form's official title is LIFE CYCLE COST ANALYSIS SAVINGS-TO-INVESTMENT RATIO (SIR) & DISCOUNTED PAYBACK CALCULATION (LRA), and it is raised whenever an office must life cycle cost analysis savings-to-investment ratio (sir) & discounted payback calculation (lra) in a way that survives the departure of everyone involved. Memory does not transfer between assignments; a filed document does. The edition dated 12/01/1986, status ACTIVE, is what stands here, spread across 1 page(s) and about unknown fields — a count that reflects how much detail the receiving system requires, not how much the drafter wishes to give. A later edition has since been published, which is why this one remains: records executed against it must still be readable in the terms they were written.
Behind any Army form sit two separate decisions. What the document asks is settled by USACE, which maintains and revises it. Whether you raise it, and where it goes once signed, is settled by not stated. That division is the reason a form can outlive several changes in the process it serves.
Identification precedes substance for a structural reason. Name, identification number, organisation and date of preparation are how the finished document is located in a file or a database; the body of the form is what someone reads after the search has succeeded. Spell the name as official records spell it, since the search runs against those records and not against habit.
Much of the form's behaviour follows from its being a fixed page. Tab order was set at build time along the reading sequence, which is why tabbing catches boxes a pointer passes over. Exclusive groups release one choice when another is made because a record cannot carry two answers to a single question. Single-line fields refuse to wrap because every entry must print where the layout expects it — text beyond the width is lost at the margin, visible on screen to the end. That is what remarks areas and continuation sheets are for. Marking a field that does not apply matters for a related reason: emptiness is ambiguous, and a reviewer reading the file later cannot distinguish an omission from a decision.
The signature is the point at which entries become an assertion someone stands behind, so it follows everything else and its absence leaves a draft. Countersignatures by reviewing, approving or witnessing officials each carry their own weight and are dated at signing, which is how the file preserves the order of responsibility. Seen that way, the familiar errors are not clerical trivia: an unanswered mandatory field, digits transposed in an identification number, day and month reversed, and residue from a reused file each put something false or unresolved into a document that will be relied upon.
The Privacy Act statement is on the page because collecting personal information requires the collector to disclose the terms first — the authority relied on, the purpose, the routine uses, and whether an answer is required or may be withheld. That order is the point: the statement is read before the entries it governs, since consent given afterwards is not consent. Once completed, the copy is a personal record and carries the handling obligations that attach to one.

Why several files for one page? Because the form has to be completed in a headquarters and in places without a workstation, and PDF covers both. The fillable pdf holds interactive fields that fix each entry in place and remove handwriting from the equation. The printable pdf is the same layout without those fields, meant for a printer and a pen. Neither is a lesser copy of the other; each answers a condition the other cannot.
Software determines whether an entry lasts. A browser viewer is designed for reading, and several will take typed input into fields without any means of writing it back — the text is simply absent when you reopen. A standalone reader handles the form structure properly.
No charge and no account apply: these are published documents, and access to them is not something a distributor is entitled to price.
The routing in not stated decides where the document goes — a named office, the administrative channel, or the individual's file — and the records schedule for the series decides how long it stays. Neither is a local judgement, because a record system loses its meaning if each office keeps things for its own preferred interval. Copy the form before submitting it.
Forms cluster by series and number for the same reason files do: shared proponency and a shared prescribing directive usually mean a shared process. So a document in the DA series referenced on the face of another is generally part of the same transaction, and continuation sheets, cover sheets and transmittals belong to the package from the outset rather than arriving after a query.
An edition marks the form at a point in a process that keeps moving, and the date printed on the page is what distinguishes one from another. Since a saved file never announces its own obsolescence, compare its date against the current edition before using it again. Prior executions remain valid: the change applies forward, and a record is read against the edition it was written under.
One boundary should be stated clearly. What is distributed here are copies of published Department of the Army forms; the site is independent, issues nothing of its own, and holds no position in the system it describes. Proponency, prescribing directives and retention schedules operate without reference to it. Consequently nothing here is legal advice and no assurance about acceptance is possible. Questions about a particular entry, a requirement or eligibility belong with USACE or your servicing administrative office.
