This system of prioritization is known as 'aggro' (aggression), and mastering it is the most critical mechanical skill in the game.
This article will dissect the mathematics of sightlines, retargeting, and unit hitboxes to help you manipulate the AI flawlessly.
The Concept of Sight Range
When a unit is deployed or finishes destroying a target, it scans its specific sight range for the closest valid enemy.
As long as you place a building just barely inside the tank's sight range, the tank will alter its path and walk toward your building.
Use the arena tiles as a visual guide.If a unit is already locked onto a tower, it will ignore closer targets.Adjust your placements for air threats.
Advanced Aggro Tricks
Large tanks have massive hitboxes, meaning melee defenders can attack them from slightly further away than smaller troops.
This highly advanced technique, known as 'body blocking', requires absolute precision but can save hundreds of tower hitpoints.

Practice Makes Perfect
You must spend hours in friendly battles practicing these specific interactions until they become pure muscle memory.
You will no longer panic when a massive push approaches; you will simply calculate the optimal placement and watch the AI dance to your tune.
