Joint Ops Weird Symbol

[.DareDevil.]

Ok i was playing in a nova server, Monsoon 2!Im not sure if it was just to show you the host at Novaworld was observing server or what but a weird symbol i have never seen appeared other night.Ive been playing Joint Ops few weeks now and never seen it but it look like the novaworld logo and it blinks red on and off!
Anyone know what i means for sure?Thought i might post it in here instead of pming someone in case someone else needs to know!I dont have a picture because it either wouldnt shwo up on ss or something cause i know i took ss but isnt showing on any in my game folder.
