Combat tactics[1] are determined for both sides at the beginning of a battle and afterwards every 24 hours[2].

Each side has a weighted list of available tactics to choose from based on current phase, commander skill, researched techs and some other criteria (see the list below). In a non-ironman game, console command debug_tactics shows all currently valid tactics and their weights.

The mechanics for picking counter tactics are not completely clear. When one army has an advantage in this regard, the following tooltip is shown:

This side currently has the Initiative because of their higher Recon among its divisions, or because their leader has higher skill level. This means they will get an extra chance to pick a counter tactic versus the other side when picking.

This tooltip seems to indicate that it does not matter by how much commander skill or Recon level are higher, only one extra chance is given anyway. The extra chance is not displayed in the debug command output and is therefore difficult to quantify.
