The listing is by unit. Within each unit page the illustrations are in chronological order. Although in Russian, the date is in Arabic numerals.

Note: The top of the column says Армия до Петра I [Army to Peter I] followed by Армия Петра I (1700 г) [Army [of] Peter I (1700)]. These headings only apply to those topics if you click on them - not the entire list.
