Its 30 seconds of full illumination then the flare dies but the area under the flare is still revealed for a further 10 seconds.
amen brother, even a cut to 20s illum time is fairer. 30s is A LONG time in current state

imo vet1 seems better as other stock recon are gained on vet. heck a 222 get its extra vision at vet2!
quite game breaking in late game, where a sov just get a mortar for map hack. that time you are dealing with all unlocked abilities and arty and long range tanks
and a wafer can't do much against 6 man mortar
