Well you've probably got a choice of two formats for the Rifle Bns of the Rifle Regts. The Mar42 organisation concentrated the 50-mm and 82-mm mortars in a separate Mortar Bn within the Rifle Regt, and left the Rifle Bns with;
Bn HQ (4 officers, 1 political officer)
Signal Pl (1 officer, 16 men)
Supply Pl (1 officer, 15 men)
Medical Pl (1 WO, 6 men)
Atk Rifle Coy (4 officers, 1 political officer, 43 men) – divided into two Pls, each of four Squads, with two atk rifles per 5 man Squad, total 16 for the Coy.
MG Coy (5 officers, 1 political officer, 85 men) – in three Pls of four HMGs each (7 men per MG), total 12 HMGs for the Coy.
Three Rifle Coys, each 5 officers, 1 political officer, 169 men. Coy HQ 2 officers, 1 political officer, 2 Sgts, 2 snipers, 1 runner. Coy Medical Squad 5 men. Three Rifle Pls, each with 1 officer, 1 Pl Sgt, 1 runner and 3 snipers in Pl HQ. Four Squads per Pl, 12 men each. Each Pl only authorised 3 SMGs and 3 LMGs, so not enough for one of each per Squad.
Total Bn 30 officers, 6 political officers, 1 WO, 672 men.
A revised Regt was authorised Jul42, that returned the mortars to Bn level.
Bn HQ (3 officers, 1 political officer)
Signal Pl (1 officer, 10 men)
Supply Pl (1 officer, 11 men)
Medical Pl (1 WO, 4 men)
Atk Rifle Pl (1 officers, 22 men) – divided into three Squads, each with 7 men and three atk rifles.
MG Coy (5 officers, 1 political officer, 52 men) – in three Pls of three HMGs each (5 men per MG), total 9 HMGs for the Coy.
Mortar Coy (5 officers, 1 political officer, 55 men) – in three Pls of three 82-mm mortars each, total nine for the Coy.
Three Rifle Coys, each 5 officers, 1 political officer, 138 men. Coy HQ 2 officers, 1 political officer, 2 Sgts and 1 runner. Coy Medical Squad 5 men. 50-mm Mortar Pl (1 officer, 10 men, three mortars). Three Rifle Pls, each with 1 officer, 1 Pl Sgt, 1 runner and 2 snipers in Pl HQ. Four Squads per Pl, 9 men each. Each Pl now authorised 4 SMGs and 4 LMGs, finally enough for one of each per Squad.
Total Bn 34 officers, 6 political officers, 1 WO, 568 men.
Divisional level recce is the only thing I've got much solid on, and it was pretty much just Rifle Pls, but without LMGs. A previous discussion can be seen here -

Rifle Divisional Sapper Bns were pretty much just two Coys of very lightly equipped troops. No fire support and not much in the way of tools.
I've not seen anything detailed on Naval Infantry, summaries would suggest they were based on Rifle unit organisation, but beefed up somewhat.
I'd go for the reprint, the Red Army companion I think; a previous discussion here had me thinking I'd lost the ability to read and count, but turned out my older copy has been superseded, with another poster quoting from updated different version.
