OmanReported count for M728 CEV. Service scope: Royal Army of Oman; does not replace a national total. 1 distinct count cell(s) from the same source list; shared rowspan cells counted once. Retired, wholly reserve and on-order rows are excluded; the reported count retains any explicitly mixed stock scope in the quoted row. Count column(s): quantity: 3. Origin: United States. The listed variants/roles are the scope, not an immediately deployable count. The components do not establish one inventory census date; the stored date is the retrieved source snapshot.
