Crossfire
Two positions covering the same ground from different angles, so a vehicle angled against one is flat to the other.
Also known as cross fire, crossing angles.
Armor only works in one direction at a time. Against a single opponent a vehicle can angle, sidescrape or go hull down, and against two that are wide apart it cannot: whatever it presents to one is exposed to the other.
Setting up a crossfire is the cheapest way for a team to beat armor it cannot penetrate frontally, and walking into one is how a strong vehicle dies without ever being outplayed individually.
