The search for an answer to find success within armoured warfare every time is well sought after. Finding the answer to success every time might be hard to find. However to possibly find it research has to be made on the subject. The purpose of this study is to better understand why the American forces at the battle of 73 Easting had such success at dismantling the Iraqi defence. The study uses a Swedish made success model where the steps are applied to the American forces actions at the battle. Then the actions are analyzed to find out whether the American forces followed the steps or not. This study aims to contribute to the general research of success within mechanised/armoured combat. It contributes to the mentioned research area by providing a new perspective on why the American forces had such success. Furthermore it contributes to the specific research area by providing an application of a success model. This study concludes that the American forces applied the majority of the steps, deployment, intelligence, manoeuvre and breakthrough, high tempo, surprise, shock and organisational breakdown to achieve victory. The study comes to this conclusion by using several operationalized questions based on idealmodellen and then answers the questions by using the gathered material.
