The RAAF operated Hercs into Vietnam almost on a daily basis for 12 years duing the conflict there. Whilst the Hercs were fired at on the odd occasion - (and not always by the other side!!!) - as far as I'm aware, they never took a hit in Vietnam.
However, a RAAF C130 did take a round in the tail during the Vietnam years... in the circuit at Laverton(!) The idiot - (I seem to remember he was actualy a 'blunt' RAAF SNCO) - was upset at the noise the Herc was making doing night circuit training and so he took his trusty .303 out into the back yard and let fly. (Law abiding citizens could own a rifle in those days.)
Sadly, these idiots with lasers have no idea of the possibly disastrous consequences of flashing their 'toys' at an aircraft, and I suspect the courts won't treat the offense with the seriousness it deserves. God help us all if some people who do understand the potential of these very dangerous devices take it upon themselves to use them against military and civil aircraft.
