15:2 gotten the victory. The heavenly sign pictures the overcomers (Revelation 12:11) of the great tribulation (also see Revelation 7:14), the last 3½ years under the absolute rule of the beast. Most of these will be martyred, then eventually resurrected and raptured to join the saints of earlier ages, probably at the end of the tribulation, and this presumably is the assembly shown to John in the sign.
