It'd be pretty simple. All the basic concepts required for its implementation is already in the game.
* Make up an aiming system simular to that of the bomb-sight in bombers
* If the intended target is flying steady at a set altitude, set an "aiming reticle" or "binocular view" or something, select the intended target with the key as you would select a padlock targert. It will zoom in and "lock-on" the target, and then you can press a key to set shell bursting alt.
* Like the bombsight, the longer you hold it down the more accurate the altitude info will be calculated and set for the gun. And then, like the 5" gun, the gunner will have to move the gun's bearing and lead angle manually and fire away.
* If the bomber pilot, seeing flak puffs appear around his plane, changes his alt, then the 88mm gunner will have to "recalibrate the alt info". Ofcourse, the gunner will have no direct hints that his aim is right or wrong, or if the buff changed alt.
* This way, it won't be as destructive and "easy-mode" as those annoying 5" guns in capital ships. If bombers, or some other planes such as jabos, are detected early and they fly straight and level, then they'd have high chance of being aimed accurately by existing 88mm batteries.
* You will also be able to switch the guns to "direct fire" mode - which will basically fire the guns just like the 5" guns without alt calculation, except the effective range will only be within 3.0~4.0k distance as a gameplay concession. This mode is to shoot at low alt targets that rush into a field such as jabos or deck buffs, or, when using AP ammo, shooting tanks.
(The firing rate would have to be a bit slower than a 5" gun in this mode to prevent abuse)
* So basically, a fighter like aircraft that moves around and changes alt a lot, wouldn't have to worry much about 88mms unless a lot of 88mm guns are working together. The 88mm will mainly pose a threat to jabo fighters enroute, and bombers high and low, and tanks, when AT 88mms with AP shells are set up.
* The 88mm gun would not be a set gun at field. The players can up a 88mm truck and tow it, and set the gun up where he pleases. So, many players will be able to take out the 88mm truck and set up a nice battery of 88mm AA guns where it's needed.
It'd add a lot to the game.
For instance, an anti-tank defense can be set up, consisting of multiple 88mm batteries with AP shells. It would be virtually impregnable to GV attacks.
People may set these defense perimeters around towns. In this case, an air-raid would be needed to take the AT guns out first. The defenders probably would need to set up AA vehicles or AA 88mm trucks around the AT 88mm batteries to defend.. and etc etc.. various situations.
Or, if a GV spawn point is somewhere in between two hostile fields, setting up large amounts of AA 88mms in this spot would be greatly helpful in taking out enemy fighters/bombers enroute to a friendly field. In this case, a ground war may break out, due to this fact, which hostile forces would fight to claim the sweetspot for setting up 88mm guns.. and etc etc..
Just having those 88mm guns, attached to tow trucks, would make the game much more fun!
