I can't believe the debate going on in this thread, and all of the inaccuracies being thrown around all over the place.
First, I want to start with Gogf's comment on the American Civil War. In order for an attacker to "win" in the American Civil War, he usually needed superiority of at least 2 to 1 (3 to 1 if assaulting a heavily fortified position). This increased later in the war as rifles became more accurate and rate of fire of said rifles increased.
To give a few examples:
The Battle of the Wilderness, fought in May, 1864, resulted in 17,000 Union casualties, compared to 8,000 for the Confederacy. Union Army was about 100,000, Confederate Army about 60,000.
Gettysburg, fought in July, 1864, resulted in 15,000 Union casualties, and 20,000 Confederate casualties. Union Army was about 90,000 (though outnumbered badly at times on first day and parts of the second), Confederate Army about 75,000. Confederates were the attackers here.
Fredericksburg, assault on Maryne Heights, resulted in over 12,000 Union casualties, and a couple thousand Confederate casualties. Union assault force was about 60,000, the defending Confederate Corps had about 30,000. The reason why Union casualties are VERY high here, is because they were assaulting Confederate positions which were heavily fortified, providing mutual fire support, and the Union was attacking across a river, and up a steep bank.
I've read over a dozen books on the American Civil War, have done alot of research for the ACW scenario, and have had such research backed up by the best historian on these boards (by far).
This is the war which made Cavalry pretty much obsolete. And, contrary to popular belief, Artillery is not what caused this (Artillery only caused 9% of military casualties during the American Civil War).
Saying the attacker won 50% of the time is completely wrong. Given equal numbers of troops, the attacker would usually lose unless they executed a daring plan which worked, or were going against a completely inept enemy commander (Chancellorsville is the best example of both).

Machine Gun: Defensive unit, poor range, once gotten to was dead meat. It needs Infantry to survive and do its work. What I would do personally, is this:
Assault Infantry - 9/9 (A/D)
Machine Gun Infantry - 7/11 (A/D) (defensive bombard, no range, 1 rate of fire)
Personally I would adjust these slightly more in favor of the defense, while reducing Civ3's grossly inaccurate defensive modifiers (such as I did for ACW). But, this would be a good step in the right direction, and compromises the 2 conflicting views in the thread, while also preserving 1) gameplay, and 2) some historical realism.
You use the Assault Infantry on offense, the Machine Gun Infantry on defense.
I would not make Machine Guns lethal land bombard, their effectiveness is highly overrated. The next section on Artillery will state why.
--------------------------------------------------------------------------------
Artillery. Artillery caused almost 1/2 of total casualties during World War I. It should KILL. Also, the quote by Lynx, that only 1,000 to 2,000 guns were used per assault is a bit inaccurate. World War I was an artillery war. Some assaults used over 10,000 massed guns over a small frontage, to try to achieve a breakthrough. However, as he also stated, these guns were used to support an assault by 100,000 men or more (1 or more Armies actually (average Division about 15,000, 2 to 3 Divisions in a Corps, 2 or 3 Corps in an Army so your average Army would be anywhere from 60,000 to 135,000 men, plus support troops, so he's correct essentially)).
Howitzers are high-trajectory guns used to bombard enemy positions from a moderate distance.
Field Guns are low-trajectory guns used to support an attack.
Mortars (haven't seen any debate on these) are VERY high trajectory guns (over 45 degrees).
----------------------------------------------------------------------------------
6/10 Civ3 Infantry. Its actually quite accurate if portraying WWI Infantry. However, its the excessive Civ3 defensive modifiers which make it useless on attack. And, the way Civ3 combat is calculated (it should be calculated for "stacks" of units, instead of just 1 unit vs. 1 unit).
Being in a large town (metropolis) did not instantly double a unit's defense. A hill did not instantly increase a unit's defense by 50%.
The other problem, as I touched upon a second ago, is the way combat is done in Civ3. It's done unit vs. unit. Its like saying, we're only going to attack you with 1 division, and you're only going to defend with your strongest division. When it should be, we're going to hit you with all of our divisions, and all of your divisions are going to have to prepare to meet it.
This would make the 2 to 1 numerical superiority a requirement for say American Civil War time period (think of 2 attacking Infantry units as 12 attack instead of 6, going against 1 defending with 10 defense, it starts to make sense), and this requirement should be higher for World War I, as most assaults (especially on the Western Front from 1915-1917) were against HEAVILY fortified positions.
Unfortunately, combat isn't resolved this way in Civ, so you have to make some compromises.

Lynx, what does your comment about ACW deserving a title mean? Is it meant as a good thing or a bad thing? And what kind of title?
Quote: No im not saying you need EVERY one, (ACW probably would be the only one with that title) but a few good makers who have posted recently would disprove my idea. Good luck in doing so.
