I don’t know why I haven’t brought this up sooner, but I have a question. Does anyone else experience frequent tank kill bugs? I have noticed that if I shoot a doomed tank which has just had a grenade shoved into it with an automatic weapon (SMG, AR, etc) that I get the kill for the driver and a wraith/scorpion assist. These are awarded if I am shooting the tank at the instant which the grenade goes off. The person who planted the grenade will get the wraith/scorpion destroyed medal, but not the kill for the driver.
I have noticed it happening a lot the past few days and I feel bad for the people who do all of the work. Is this a bug?
This already happend to me several times and I think its an bug.
Something similar happened to me a little while ago in Castle Wars, blew up a mongoose right as the driver leaves it and despite not killing him I got the medal for destroying the mongoose.
I have seen people shoot vehicles with a laser and me get the laser while i planted the grenade. This glitch goes for any vehicle you can plant a grenade on (Wraith, Tank, Mantis)
I think it is just with the timing and with the destruction of vehicles. I have a clip where I have been in the back of a gungoose nade spamming on defense off a warzone assault match and gotten credit for a double kill using a railgun. I got the two railgun kill medals, wraith dstruction assist, and the double kill medal. All the damage I did to the wraith was bounce a grenade off it as it was exploding.
This glitch has been around for as long as I can remember. It’s nice to get all those grenade and splaser kills by shooting vehicles with a br though 
Sucks for the teammates who actually earned them lol
yes is weird, but it happend to me several times, like this
It’s the same with anything. It’s always been a thing in halo I do feel like it’s easier in halo 5 though
Yeah, it’s an old glitch. Every once in awhile I’ll troll my teammate who planted the grenade and shoot the tank before it blows up since I know I’ll get credit for it.
It definetly seems more common now at least to me.
This has been a glitch with vehicles since Halo Reach. Basically there’s a delay between when a killing blow is done to a vehicle and when it actually blows up after. If someone damages it in between, that person will be rewarded the kill with the weapon that doomed the vehicle even if they aren’t carrying that weapon.
Wraiths and Tanks are the worst for this because they have like a 1 second delay from being “doomed” to blowing up. Warthog and ghosts are.musch harder because they blow up nearly instantaneously.
The real issues are crouching in a mantis to avoid the planted nade and driving backwards in tanks to survive a rear planted nade.
