alike “Why do the same machine guns use different ammunition belt compositions?”…
(For example, the French Hispano and British Hispano have different belt compositions, and the SAP ammunition found on the American Vulcan is not available in Japan)
Did Gaijin design the machine gun’s belt composition separately to match historical accuracy?
As far as im aware they’re generally based on IRL composition, but not too strictly. IE M61A1s use similar belts depending on era, regardless of what the nation actually used, or dshks on certain soviet tanks getting AP(c) rounds despite cermit rounds never being distributed to tank crews.
Historically, 20mm belts would have a good mix of types in the sequence for a few reasons.
Stuff like tracer goes without saying, gives your pilots a reasonable idea of where their rounds are going.
SAP was considered quite good for ground-targets.
HE/Inc was good for softer targets, and so on.
AP for, well Armour Plate. Not tank armour, but the plating on the side of a ship for example.
The general idea being that in a typical short burst of cannon rounds - you’ve got a decent chance of hitting with something that will do damage to the unfortunate on the other end.
Be in no doubt however - if a 20mm shell hits anything short of a tank - it doesn’t really matter what the precise loading is. It’ll make a mess.
RAF Typhoons are known for their rockets for example, but anecdotal evidence suggests it was the hail of 20mm cannon that tended to properly mess up ground columns as much as anything else.
A clear no - at least for bombers you need less than 3 minutes to find out that heavy US bombers used more or less exclusively AP-I rounds mid to late WW 2. They realized like others that tracers are actually distracting and were not really useful.
But - to be fair the tracer rounds are a aiming support in wt, so it looks like that things like game play support play a role too.
I think “based on” looks somehow right.
The main question is the issue that the first round in the belt still determines the muzzle velocity of the entire belt. So even if you have way faster projectiles in your belt, if the first round in your belt has a slower ammo type all subsequent rounds are not faster than the first.
Also here - no secret, you find a lot of vids on yt describing this.
I think it was an intentional thing to give consistensy to shell trajectory but has led to a meta where its sometimes better to sacrifice a better frequence of a valued shell for more velocity.
Would like to see custom belt loads so that we can just pick whatever shell we want (however the velocity standardisation would make this slightly exploitable)
