Stalin had in 1941 ordered mass wave attacks with anything that a commander had without making adequate preparations due to the desparation at the time, but in 1942 onwards Wave tactics became far less frequent.
Once equipment and munitions production finally kicked in and numbers switched to the Russians in all fields the tactics changed as things became more stable, attacks with large amounts of infantry, artilly and tanks was common but it wasn't done helter skelter, there was always strategy involved, except with alot more men and material used.
Try to research the "Russian School" of thought which used a combination of numbers, mobility, and the toughness of the average Russian to win in "shock attack" engagements. The Russian Civil war (the miliary side) is a better view of this.
The Chinese under Mao favored Mobile "People's War" doctrine, of "luring the enemy in deep", utilizing the peasant masses to form a "wave of humanity" to stop the enemy in which the red army could become "fish among water", and favored flexible tactics of attacking the enemy where they were weakest to weaken them in whole.
These tactics first used against the GMD in the Jiangsi Soviet Republic, then against the Japanese in WWII, and finally again against the GMD in the second Chinese Civil War.
I'm certain that they were used to drive the Americans back to the 38th parallel but I don't know much else after that.
