considering that many units differ in how often they attack, i thought it'd be interesting to set up a list of units by damage per second (more specifically, damage per frame/game step). i used these as a resource:
http://classic.battle.net/scc/protoss/pstats.shtml
http://classic.battle.net/scc/terran/ustats.shtml
http://classic.battle.net/scc/zerg/zstats.shtml
this has probably been done already by someone, but i haven't seen it yet. this is of course utterly useless information strategically, but i thought it'd be fun to do. these all use numbers without any weapons upgrades, assume 0 armor, and assume that they do full damage to their target type (in the case of explosive and concussive damage).
reaver - 100/60 = 1.667
archon - 30/20 = 1.5
stimmed firebat - 16c/11 = 1.454
ultralisk - 20/15 = 1.333
turret - 20e/15 = 1.333
dark templar - 40/30 = 1.333
scout (air) - 28e/22 air = 1.27
sunken colony - 40e/32 = 1.25
spore colony - 15/15 = 1
seige tank (sieged) - 70e/75 = 0.933
goliath (air) - 20e/22 = 0.909
cannon - 20/22 = 0.909
wraith (air) - 20e/22 = 0.909
battlecruiser - 25/30 = 0.833
crackling (attack-speed upgraded zergling) - 5/6 = 0.833
seige tank (unsieged) - 30e/37 = 0.810
stimmed marine - 6/7.5 = 0.8
valkyrie - 6e/64*8 = 0.75
firebat - 16c/22 = 0.727
zealot - 16/22 = 0.72
vulture - 20c/30 = 0.667
guardian - 20/30 = 0.667
dragoon - 20e/30 = 0.667
hydralisk - 10e/15 = 0.667
corsair - 5e/8 = 0.625
zergling - 5/8 = 0.625
goliath (ground) - 12/22 = 0.545
lurker - 20/37 = 0.541
ghost - 10c/22 = 0.454
marine - 6/15 = 0.4
scv - 5/15 = 0.333
mutalisk - 9/30 = 0.3
broodling - 4/15 = 0.267
scout (ground) - 8/30 = 0.267
wraith (ground) - 8/30 = 0.267
devourer - 25e/100 = 0.25
probe - 5/22 = 0.227
drone - 5/22 = 0.227
arbiter - 10e/45 = 0.22
carrier - N/A, no cooldown rate listed
infested terran - N/A, can't attack more than once
scourge - N/A, can't attack more than once
so, attack speed matters! oddities:
- the devourer's attack speed is so slow that it does barely more damage than a probe, drone, or arbiter
- ignoring that its damage is concussive and ground-only, a stimmed firebat is actually the highest damage-dealing unit the terrans have: significantly more than a seige tank in seiged mode
- the air attack of scouts is fairly powerful, it's near the top of the list
- a single crackling does the same damage per second as a battlecruiser
- in theory, the highest-damage terran army would consist of turrets, seige tanks, and stimmed firebats, for protoss it'd be reavers, dark templar, and archons, and for zerg it'd be ultralisks, cracklings, and sunken colonies
