A couple of areas where I think the Wiki kinda fails currently and I would like to see added
Aircraft:
Currently, Countermeasure counts are not shown, it states that any aircraft has flares, chaff or flares/chaff, but doesnt give a figure of how many, or type. This information would be very useful when comparing aircraft. This should also be included in the aircraft comparison.
Ammo belts for external gun. Currently, Aircraft with internal guns have all available belts listed, but if the gun is external, such as on an aircraft like the Alpha jet or Sea Harrier, then the belts are not visible. This information should be available to view regardless of where the guns are mounted.
RWR / MAWS coverage. Another area of information that would be useful to have is if the FoV of these sensors were available
Radar coverage, again, FoV/FoR isnt visible anywhere on the pages.
Ground:
Main one that coems to mind is the HP/T within the vehicle comparison, this is an important piece of information and it is currently missing from the comparison page. This information should be included.
Naval:
An area that kinda annoys me (and this annoys me kinda everywhere tbh) is the switch between mm in some places and inches in others. So a toggle button on a naval page to toggle figures between mm and inches would be good
All 3:
Choose units of measurement, for example for aircraft: all figures are given in km/h for speed and m for alt, it would be good to have an option to select the desired unit of measurement for these figures, as I personally use neither for in-game figures and it requires constant convertion. Perticuarly for things like flap limits. Same thing for ground vehicles and naval vehicles, it requires convertion to make sense of for someone not use to these figures
These are the main things Id like to see improved about the wiki, but would be interested ot see what other ideas people have for making the wiki better
