Those are Variable Time (VT) fuzes. There's also time fuzes, however, that also function as airburst. These are much lower tech and require mortar/artillerymen to be actual mortar/artillerymen (number crunching/book reading). The optimum height of burst for the VT fuzes is actually 7 meters. For the time fuzes optimum HOB is 20 meters as everyone has said.[R-DEV]Sniperdog wrote:The airburst rounds IRL (the kind that are depicted in game) have a sensor on the front that causes detonation when it detects the ground ahead of it.
Accordingly no calculation is required to set the airburst round, it works automatically.
Nice guide by the way.
Note: From an earlier comment I understand this isn't in game but firing VT (airburst) in a urban setting is ridiculously dangerous. The fuzes inside those rounds detect when they are 7 meters above the ground. What this fuzes determines as "the ground" may be the ground...or the roof of a building 400 meters in front of your target...or a tree. You would use time fuzes in that case.
Also note calling them airburst rounds is technically wrong. The round itself is HE. What causes it to function in the air is the fuze.
Not trying to be a smartass just giving you guys heads up IRL knowledge. In case anyone gives a shit (don't be bothered if you don't, the infantry guys don't care either).
