How to unlock the War of Attrition achievement in Supreme Commander - Definitive Guide
During any mission, after your army destroys the units or buildings in an area, have your Engineer or ACU capture the Concrete wall sections owned by the CPU. They take no time to capture and count toward the total or units captured. Your troops virtually never destroy them accidentally, and there are often many more than 100 on a single map.
The achievement does not pop until you save or end the game.

You will get this when you go for Controlling Presence. If you want to do this first however, capturing mass extractors and other small buildings is the easiest way to go. Let the AI build all over the place on a large map then send engineers out to capture those points. Alternately just play through all the campaigns and this will unlock. Note also that the neutral (tan colored) buildings and all wall structures count for this as well.
