There are three bootcamps in total on the Savage map. The Alpha one is situated on the smallest of the three islands, and it's the best one. First of all, it is located under the hill -- the highest point on the map with an excellent overlook, which can be used as a perfect spot for sniping in all directions.
Secondly, it has watch towers, which again can be used for great sniping or vantage points. And lastly, it is located very close to another cool spot -- Manufacturing, the only real place for urban warfare and real squad action.
