# I don't remember all the considerations that went into our original warhead damage model.
# But looking at the formula it looks like they all do 100% damage at 0 meter hit,
# and warhead size is only used to determine the decrease of damage with distance increase.
# It sorta gets the job done though, so I am hesitant to advocate that warheads above a certain
# size should give 100% damage for some distance, and that warheads smaller than certain size should
# not give 100% damage even on direct hit.
# Anyway, for hitpoint based assets, this is now the case. Maybe we should consider to also do something
# similar for failure mode based aircraft. ~Nikolai
