Вообще-то автор прямо сказал:
1) The mentality is highly adversarial; these aren't parahumans who play nice with other parahumans, and this includes them not cooperating with other members of the Elitnaya. There's a lot of politicking and backstabbing going on behind the scenes (to the point that Russia is almost divided in four), and each member of the Elitnaya maintains ties to certain sub-factions, individuals and interests. Favor is curried, and virtually every mission the Elitnaya are mobilized to involves hidden motivations and sub-goals in service of sponsors and secret masters (human, not Master). Put two of these guys on the same mission, and their interests may collide. Keep in mind, these guys got their start being used to hunt other parahumans. The relationship is largely 'shoot identified parahumans on sight', or, in the case of Elitnaya vs. Elitnaya, waiting until they're in private before orchestrating one another's murders.

2) Overall, Russia has suffered more at the hands of Endbringers and S-Class threats than most, and it was the lack of faith in the government's ability to protect the people (and the aftermath of losing Moscow) that led to the fall of the U.S.S.R. and rise of other forces. It has less parahumans and less structured organization than most, so it tends to respond to Endbringer or S-Class threats with military strength more than most other national players.

Как из этих слов можно сделать вывод что кейпы России "дружно" сражаются плечом к плечу против Губителей я не понимаю.

Руские кейпы увлеченно уничтожают друг друга, а против Губителей выставляют обычные войска, что закономерно приводит к катастрофам.
Зато пример хороший - прижмете кейпов - будет как в России. Против губителей придется слать обычные войска...
