Wild West forts weren't built to withstand sieges, simply because the Natives had no opportunity to use artillery or even massed assaults (except for very rare situations). The Army had no need to prepare for any sort of large scale battle, and instead needed to construct something that could at least keep the Natives out as well as to secure an area and give a location that soldiers and civilians could retreat to if necessary.
Besides the fort itself and soldiers, Playmobil 5245 Western: Fort Brave set also came with two Native Americans and their horse, plus weapons. The horse is different from that of the United States Cavalry and both American Indians are not identical.
Indigenous peoples of the United States are commonly known as Native Americans or American Indians, and Alaskan Natives. The European colonization of the Americas forever changed the lives and cultures of the peoples of the continents. Although the exact pre-contact population of the Americas is unknown, scholars estimate that Native American populations diminished by between 80 and 90% within the first centuries of contact with Europeans. Native Americans suffered high mortality rates due to their lack of prior exposure to these diseases. The loss of lives was exacerbated by violence on the part of colonists who frequently perpetrated massacres on the indigenous groups and enslaved them. (source: wiki)
