re: 5 silverback Males vs 15 Gray/timber wolves

Given that leopards are known to fight on equal footing with gorillas, I’d say this one could go either. Gorillas are also prone to excess bleeding. A few good bites could swing the battle quickly as the gorillas tire. Keep in mind that the wolves are just as big if not bigger than the gorillas, but they weight about 70% less. A gorilla would only be able to focus on a single wolf at a time and if the wolves work as a team, they may be able to cut them down slowly over time. If the gorillas were to somehow work as a team, they would sweep, but 5 silverbacks in an area would result in a melee where to wolves pick off whomever is left.
