There are at least 6 BTGs of the Rosgvardia inside Ukraine. The one in Kherson is involved in fighting.

Thus, perhaps he can't send all of them to Ukraine (and I doubt he would ever do so: after all, the Rosgvardia are, de-facto Putin's counter to a possible coup attempt from within the VSRF), but he has already sent 'more than enough' of them there.
