Do Catachan Armoured Regiments exist?

So I was thinking of making a Catachan Leman Russ tank company but when I looked on the 40k wiki I couldn't find and armoured regiments, they were all Catachan number regiment. Most of the other guard regiments have what the regiment is in the name. I thought maybe the regiments could have armour and infantry combined but the wiki says the guard doesn't do that to prevent rebellion or something. So do the Catachans not have armoured regiments or do they just not include it in the name?

Edit: I was silly they do exist just none are listed in the notable regiments section
