I dont know, i did not hear not an single warning since i play BS on FC2 serrvers and later one tester confirm to me that something is broken on FC2.0 host - ka50 client relations.
Anyway, before patch every tank(only T-55 not, very old peace of iron:)) and every vehicle with ATGM,avengers,gepards,ect used to alarm LWR...
P.S.iI was thinking about something, EOS from russians birds have laser range finder too.Does ka-50 LWR have capability do detect that type of laser ilumination , in RL i mean, i all ready know that something like that is not simulated in DCS.
