It seems that Brit AA is trash compared to the US M16 halftrack.
I was thinking that relic balanced each faction to have a similarly effective counter to planes.
Apparently 2 centaurs struggle to shoot down even 1 plane.
I guess that's one thing that the US does better than brits at least.
On a more serious note, that's even worse gameplay design than I thought. If there's no US player, then the brits are seemingly shit out of luck for AA.
It is a bit odd actually. All aircraft in CoH3 have the following durability stats:
Health | 280 |
Armour (Front/Side/Rear) | 10/5/1 |
Target Size | 20 |
Here are the stats for some common AA weapons:
Weapon | Crusader AA | CWT Truck AA | Flak 36 | US AA Halftrack | Wirbelwind |
AA Range (Max/Far/Mid/Near) | 240/240/120/60 | 240/240/150/60 | 420/420/270/120 | 270/270/120/60 | 240/240/120/60 |
Penetration Chance | 100% | 100% | 100% | 15%-100% | 100% |
Tentative (In Magazine) DPS | 54.78 | 80.00 | 91.42 | 132 | 38.91 |
Note that all of these weapons have a 100% chance to hit out to range 270 with the Flak 36 dropping down to an 80% chance to hit at range 420.
The Wirbelwind is the most interesting here - it does 180 damage to aeroplanes per burst (over 3 seconds with a 1.5 second gap between bursts) so will kill an aeroplane within its range in ~6.3 seconds but this drops to ~10.5 seconds if it needs to reload between bursts. One would expect this to be the worst AA option but it seems quite effective in game.
The US AA halftrack is also interesting in that it will tear aeroplanes apart against the rear (100% penetration chance) or side armour (30%-50% penetration chance) but is substantially worse against the front armour (15%-25% penetration chance).
I'm not sure these stats fully capture the units' AA performance though.
