Here's a whole DIA report on the tactics and ORBAT of the typical Soviet tank battalion circa 1977
In short: The deployment of the tank battalion depends entirely on it's mission. Are you preparing for a meeting engagement? Are you assaulting a fortified position? Bracing for nuclear attack? Defending? Racing through a gap to destroy or capture that nuclear missile?
In any case, the battalion's mission is given to you by your recon assets, whether they survive or not.
See this example:
Recon forces have discovered an enemy company(+)-sized element in a reverse slope defense position that is defending in depth.
So what did they see before they disengaged?
-A Mech company HQ
-A Mech platoon
-A Tank platoon
-A Vulcan AD platoon
-A Mortar platoon
-An enemy command vehicle known as the "M577"
Based on this force composition, we can tell that it's a reinforced Mechanized company. Screening BRDMs would confirm this later.
So now we have to task-organize and arrange the tank battalion based upon terrain, enemy defense, and the mission.
Let's say this axis is the main axis of attack, so we have priority for air and artillery strikes. This means full support from the RAG, as well as DAG elements.
Task organization of the battalion is ultimately the responsibility of the Regiment commander. Let's take a look at what he's come up with:
Here we haveL
-The Tank Battalion itself (Two companies T-55AM, one company of captured Leopard 2A4 )
-We're expecting close quarters combat with a dug in infantry force, so a motor-rifle company has been attached from the regiment's motor-rifle battalion
-We've spotted enemy helicopters, so a section of ZSU-23-4 are attached from the AA Company
-This battalion is the leading element on the axis of advance, so a 2S1 battery has been attached from the RAG for direct support
-Finally off-map, we have RAG, DAG, and Fixed-wing air support. In this scenario, we'll simply have the RAG of 2x D-30 batteries and a full Geschosswerfer battalion of 3x RM-70 batteries.
The battalion is organized. Now for the plan of attack.
