Introductory, adjective. See below for example.

My name is Comrade Cleef, but you, my friends, may refer to me by my first name: Comrade. Currently, I am waiting on Comrade Wofle to begin playing Nexus: The Jupiter Incident, an absolutely stellar space game, pun intended. It has two aspects to it: The real-time strategy/tactical aspect, and the planning/grand strategy aspect. I'll explain the two aspects shortly, along with Comrade Wofle.
