Cross-post; satellite will receive a Kosmos designation:

The Angara-A5DM-03 Persei (71754/2L) launcher set for an Q4 2022/Q1 2023 EKS/Tundra/Kupol launch shipped to Plesetsk on 16 May 2022.

Replacing the previously used Soyuz-2.1b/Fregat launcher?

Or same system as earlier OKO/PROGNOZ, and this one would be the GEO component ?

This one will go to an inclined HEO using the newly employed bi-eliptic transfer orbit (BETO/BTO) without the GEO insertion burn (3rd burn) being conducted. The flights primary objective is to perform the first test of BETO is risk reduction for the GEO component which will debut in a few years in addition to other heavy Kosmos/commercial payloads. Persei was modified with a new life extension kit since a BETO flight lasts longer than the other blok D family flights to date and traditional transfers Orbital methods. The EKS payload was originally scheduled on a Soyuz-2-1b/Fregat.

Thread title should be Angara 5 Persei, not Angara 1.2

Persei stage failed on its inaugural flight, why would they place an important military satellite on its next flight before testing it at least a couple of times with mock ups or less important satellite payloads?

Cause they are just throwing together what they have in the shop?

To perform more experimental orbit transfer tests.

Note it will be a Tundra spacecraft however the number is not confirmed as flight 6.

Per an RSW subscription paywall article: Persei's problems resolved

Executive summary: The loss of the upper stage was found replicated in follow-on serial numbers which was attributed to manufacturing and product hardware and software quality control issues pertaining to necessary design changes between the Blok-DM versions highlighted below. The persei for the next flight has been remediated and is ready for flight processing.
Blok-DM-03 versions currently in use by cosmodrome: Baikonur: 11C861-03 (Phase I Variant 1 and Phase-IIa), Plesetsk: 14С48 (Phase I Variant 2), Vostochny: 14C49 (Phase II).

Tundra/Kupol #7?, as #6 will launch on November 2:

It looks like the payload is Kupol. An ISS Reshetnev insider writes on the NK forum that Glonass K2 is still undergoing ground tests.
