Soon the NCR had to stray from conventional battle tactics and adopted a new strategy… attrition. Though they were severely outnumbered by the NCR, the Brotherhood was determined to win the war. At the start of the war, the NCR was crushed in nearly every battle.The Brotherhood of Steel had access to far superior technology, as well as being more rigorously trained and disciplined. That war lasted for decades and each victory for the NCR came at a very high cost. The NCR in the Frontier are mostly comprised of veterans and conscripted soldiers from the NCR-Brotherhood War.
