Imagine you have 10 cavalry next to a city and you have ten cossacks next to a city. How many attacks can you make with the cavalry? Ten. How many attacks can you make with the Cossack? Up to 30!
Let's ignore artillery for a moment. Using the Civ3 combat calculator, a typical cossack battle (cossack vs. fortified musket in a city) gives a 61.3% chance for the cossack to lose. There go 6 of your 10 cossacks right away. Of the 4 winners, only 1/3 will have 3 or 4 hps left. Presumably you wouldn't attack again with just 1 or 2 hps left. So out of 10, usually 1 but sometimes 2 cossacks will be healthy enough for a second attack. So you really only get 11 (sometimes 12) attacks vs 10
for cavalry attacks. Fine. I'll rush build 1 or 2 more cavalry and I have the equivalent. In either case it is best to have a surplus of units so that battles are never decided by depending on having a single extra attack.
As for artillery. Yes, you can redline the defenders down to 1 or 2 hps making things easier. A veteran cossack has a pretty good chance of winning twice (~80%), automatically gaining elite status. Assuming around 5 defenders for a city (usually 3 or 4 muskets plus a junk unit or two like a longbowman), a militaristic civ has a 76% chance of getting an elite while a non militaristic has 49% chance. I'll concede that this clearly gives an edge to the Russians over non-militaristics, but only at the start of a war. As more and more individual cavalry units are promoted to elite the difference steadily dimishes.
Still, there is an edge there for artillery users and I must admit I've never tried the Russians. I always soften the enemy with lotsa cannons. Hmm. Alright, guys. You've piqued my interest. I'm gonna give the Russians a try next time. Does anyone know their starting techs offhand?
