How to unlock the Scrap Metal achievement in Stormrise - Definitive Guide
While in the Campaign on Mission 4, the end of the level has 3 Stalkers. If you get a army and just attack the group of stalkers (and a boss) you will easily kill a stalker. But make sure to save right before you do. When you get the perfect save, just kill the stalker and quit out WITHOUT SAVING. Then just hit continue campaign on the menu. Repeat 27 times and you will unlock the achievement. This takes about 10-15 minutes easily.
Stalkers are bipedal heavy armored vehicles, in the Echelon army. For the trophy you have to destroy 27 of them. A good place to farm them is in mission 8. There are two stalkers right at the beginning. Secure the 3 first nodes, trying to not go too close from the stalkers. Prepare two groups of 3 Matriarchs (one for each stalker) and save your game. Now send each groups to one stalker and quit the game once destroyed. Select "Continue" from the campaign menu, then rinse and repeat until completion.
The Echelon Stalkers are mainly anti-air units. Use Matriarchs or other heavy tanks and take out 27 of them with a friend. As a general rule of thumb, if you see any unit that has an achievement related to them, save, kill, and keep reloading the save until you get the achievement in the campaign.
