Creating a new issue for this idea by @leedrake5, as it offers a more flexible option for coding the URLs.

One possible fix (and note, switching to argument defaults instead of hard links makes it compatible with the Wayback Machine for getting archival data):

russia_materiel <-
  get_data(
    russia_link,
    "article"
  ) %>%
  rvest::html_elements("li")
  
  ukraine_materiel <-
    get_data(
    ukraine_link,
      "article"
    ) %>%
    rvest::html_elements("li")
    
    materiel <- c(russia_materiel, ukraine_materiel)

Note that this requires the 'do' package to concat xml node sets.

Minor change, add the following as default arguments to the function:

russia_link="https://www.oryxspioenkop.com/2022/02/attack-on-europe-documenting-equipment.html", ukraine_link="https://www.oryxspioenkop.com/2022/02/attack-on-europe-documenting-ukrainian.html"
