   * <br>
   * This packet does not actually modify anything in regards to deployables.
-  * It merely generates the message:<br>
-  *   `"You have placed x of a possible y thing."`<br>
+  * The most common form of the generated message is:<br>
+  *   `"You have placed x of a possible y thing s."`<br>
   * ... where `x` is the current count of objects of this type that have been deployed;
   * `y` is the (reported) maximum amount of objects of this type that can be deployed;
-  * and, `thing` is the label for objects of this type.
-  * This text is not directly placed into the message's field but, rather, is a token for language-appropriate descriptive text.<br>
-  * "boomer," for example, is replaced by "Heavy Explosive Mines" in the message for English language.
-  * @param guid na;
+  * and, `thing` is the token for objects of this type.
+  * If the `thing` is a valid string token, it will be replaced by language-appropriate descriptive text in the message.
+  * Otherwise, that text is placed directly into the message, with an obvious space between the text and the "s".
+  * "boomer," for example, is replaced by "Boomer Heavy Explosives" in the message for English language.
+  * "bullet_9mm_AP," however, is just "bullet_9mm_AP s."<br>
+  * <br>
+  * When the `action` is `Success`, the message in the chat will be shown as above.
+  * When the `action` is `Failure`, the message will be:<br>
+  *   `"thing failed to deploy and was destroyed."`<br>
+  * ... where, again, `thing` is a valid string token.
+  * @param unk na;
   *             usually 0?
   * @param desc descriptive text of what kind of object is being deployed;
-  *             matches the `String` description of the object class
-  * @param unk na;
-  *            usually 4
+  *             string token of the object, at best
+  * @param action the form the message will take
   * @param count the current number of this type of object deployed
   * @param max the maximum number of this type of object that can be deployed
-  * @see `ObjectClass`
