In the old spelling :
30 Августа 1815 — Гренадерскіе Егерскіе полки наименованы Карабинерными: 1-й — 1-мъ, 3-й — 2-мъ, 8-й— 3-мъ, 14—4-мъ, 26-й—25-мъ и 29-й—6-мъ
30 August 1815 – Grenadier Jäger regiments were named Carabinier
12 Февраля 1816 — 17-й Егерскій полкъ, за отличіе, переименованъ въ 7-й Карабинерный;
12 February 1816 – The 17th Jäger regiment, for distinction, was re-designated as the 7th Karabinernyi.
Karabinernyi Regiment was an honorific title, replacing/re-naming Grenadier Jäger Regiment. Previously, the distinguished jäger regiments conserved their original numbers : 1st Grenadier Jäger, 3rd Grenadier Jäger, 8th Grenadier Jäger, etc.
After the war, this was changed to 1-i Karabinernyi Polk, 2-i Karabinernyi Polk, etc.
The term "carabinier" applied to distinguished Army regiments, not Guard. It did not, officially, apply to the Grenadier Companies or Grenadier Platoons or individual Grenadiers within regiments. However, there was some natural "over-use" of the nomenclature, un-officially.
In any case, this would be all late 1815 and later.
