Weapon and Ammo Upgrades?

Can anyone answer these questions or point me to the documentation covering how the upgrades work for weapons and ammo? (Any additional info is appreciated.)

Does the "fight strength" mean that a 200q weapon will perform at twice a 100q weapon?

Once purchased do both weapons and ammo degrade in strength? If so at what rate?

Can the upgrades be stored for future use? Or do these degrade as well?

Once upgraded do the weapons still degrade? (Making it better to upgrade at the last moment?)

It looks like weapons and ammo are upgraded while in unit form? Or can it also be done to weapons and ammo just sitting in inventory?

Does it take time for these upgrades to occur? If so how long?

Thanks to any for the help; I am confused

If anyone is willing to share any other info I'm all ears.

An average quality level of 160 for the weapons in a unit means that the weapons are 60% more effective in destroying their targets and they are also 60% harder to destroy. Very high fighting levels will become possible and will have an excellent effect on the fighting capabilities of military units.<!-/Quote-!>

Honestly, I think this is a bit open to multiple interpretations. What do they mean by 60% more effective? How exactly do they mean 60% harder to destroy? My interpretation is as follows:
H = hit rate
D = damage
Q = quality
Subscripta/d denotes attacking weapons and defending weapons respectively

So the attacking unit hits ba

Exactly what I was hoping to get in reply; thanks for the help!
