In addition to the typed classification, stamp the classification (with red stamped lettering, if possible) in the center of the top and bottom margins. When you use either of the terms Top Secret, Secret, or Confidential in the body of correspondence to denote a classification category, capitalize only the initial letter or letters. For detailed instructions regarding classified corres- pondence preparation, refer to the SECNAVINST 5510.36. "FROM” LINE: Type the “From” line two lines below the date in the identification symbol or two lines below the classification at the left margin. Allow two spaces between the colon after “From” and the beginning of the addresser’s title. The “From” line identifies by title, the official in authority (usually the commanding officer or the officer-in-charge) over the activity with cognizance over the subject that is covered by the letter. If an addressee needs to reply to the letter, he or she should direct the reply to the addresser. The “From” line furnishes the addressee with this information. Remember that all standard letters must have a “From” line. Use only long address titles in this section. "TO" LINE: Place the “To” line on the next line below the “From” line. Allow four spaces from the colon after “To” to the beginning of the title of the addressee. When the functional title does not clearly distinguish the addressee, give sufficient information as to the intended activity to assure that the letter is correctly delivered. Except when you prepare correspondence that is intended for a ship, follow the title of the addressee with the title or the code designation (in parentheses) of the office that has immediate responsibility for the subject matter. Use the complete mailing address with the ZIP code for the "To" addressee when you want the address for a record. "VIA" LINE: Place the "Via" line, if any, on the next line below the “To” line. If there is more than one ‘Via” addressee, number each with a numeral that is enclosed in parentheses: (1), (2), (3) and so forth. “Via” addressees are used when one or more activities should see a letter before it reaches the activity that it is addressed to. The numerals indicate the sequence through which the correspondence is sent. "SUBJECT" LINE: Use the abbreviation “Subj” to introduce a topical statement of the subject of the correspondence. Place the "Subj" line two lines below the preceding line of type. Allow two spaces from the colon after "Subj" to the beginning of the subject. Use normal word order. Capitalize all letters in the subject line. A letter of reply usually repeats the subject of the incoming letter. "REFERENCE" LINE: Use the abbreviation "Ref" to identify applicable references. References are previously released correspondence or conversations that have a direct bearing on the correspondence that you are preparing. Type the "Ref" line two lines below the last line of the subject line. Begin each reference citation on a new line. Allow three spaces between the colon after "Ref" and the beginning of the first reference. List references in the order that they are discussed in the text of the communication. Identify references with small letters that are enclosed in parentheses: (a), (b), (c), and so forth. When referencing a letter, you should include the following information: The abbreviated title of the originator Location of the originating activity All identification symbols that were assigned to the referenced letter The abbreviation “ltr” or “memo” The date Other types of references include publications, instructions, telephone conversations, endorsements, and messages. When documents other than letters or memos are listed as references, they should be fully identified as to origin, title, and date. Specific samples of various types of references are listed in SECNAVINST 5216.5. "ENCLOSURE" LINE: Include the abbrevia- tion “Encl” in the heading when correspondence that bears directly on the standard letter is forwarded with the letter. Place the “Encl” two lines below the preceding line of text with each enclosure notation beginning on a new line follow the colon after “Encl” with two spaces. Number enclosures with numerals in parentheses: (1) (2), and so forth. List each enclosure in the order that it is discussed in the text. Identify each enclosure that accompanies the letter by typing, stamping, or writing "Encl" in the lower right corner plus the number that is assigned to it in parentheses, for example, Encl (1). TEXT: Begin the text (or body) of the letter two lines below the heading information. When drafting a letter, begin by making the opening paragraph clear and concise. 2-10
