Hi @CalvinKlein, the group is based off the Dark Army featured in the series Mr Robot. The group is run by the upper class in China through businessmen with disguised identities; the organization is a front for turning political decisions in their favor. As so, we have our hands in everything- the drug trade, electing leaders in our favor, etc.
We aren't a street gang, therefore we have zero need for weapons when we are not conducting business. We do not need to carry guns on a daily basis as there is no one to defend ourselves from; our identities and association with the group is unknown- we are simply the upper class in a normal person's eyes. We will use guns, whether that be through defending members or war, the group will not be engaging in daily shootouts that hold no meaning.
Due to this, we will have weapons stored- whether this be for defending our HQ or high command, you can't expect such a powerful organization to not have heavy weaponry at the ready.
