Certainly not the case in naval, and don’t see any requirement for it ins the description.
However the thing that kills them DOES have to be T3 - it’s not like some dailies and special tasks where you can start with T3 and then complete them with T2
A 250LB bomb fits in the ‘under 130kg’ category. Not sure if you can get one of those in a ground arcade strike plane or not (US maybe?). I did try a few realistic battles yesterday, and SUCKED… I’m too old to see the tanks at distance ;) I did get 2/3 of the small bomb kills in my first two games, then my luck ran out.
I’m almost completely certain the kill target has to be tier 3. I experienced this with several previous battle pass challenges. I had to change which BR I was playing at because I was often killing targets that were players’ alternates below tier 3 rating.
So this is only one case… But I had the ‘Tiger’ special task yesterday, 5 kills in 5 games. I was using the 8.8 Flak, got 5 kills in the game including a T-34 (1942), and it gave me credit for 5 kills to the task. So I killed a Tier II with a Tier III and it counted in this case.
The daily tasks and special tasks don’t have this requirement that the targets you kill be tier 3, but I’m pretty sure I’ve seen it to where the challenges do require tier 3 targets.
I didnt get a bomber with 100kg bombs below when playing tanks. And I didnt get a bomber with 100-1000kg bombs, only 2/3. Heavy bombs was not a problem.
Dunno about ground, but again it is easy in naval, since you select your plane and load out, and plenty of a/c have both small and medium bombloads available.
I Just tried Air AB and RB with P47D-25 and P47D-28. None of my 1000lb bombs are counting. I’ve also tried the British Typhoon MK 1b with 1000lb bombs in Ground RB and that doesn’t count either.
I was using SC1000 which is 1000kg bomb using bf 110 G-2 plane (III. rank) on higher br than the planes br and my kills were counted.
When I was on the planes br the kills were not counted, so I assume that when you get skill matters by destroying an vehicle by 1.0 br higher, the kill will be counted. I was also trying to find answers online and one guy said that the 1000kg bombs count as medium bombs (130kg - 1000kg) and also as big bombs(at least 1000kg) so it randomly counts, sometimes as medium and sometimes as big. So I could be lucky with the higher br battles bc i only did one battle and my challenge was completed. Another guy said that by killing 2 and more tanks with one 1000kg bomb it will count as a big bomb, but unfortunately this is not true as I managed to kill 4 tanks with one 1000kg bomb and not a single kill was counted.
