Is the following a good squad composition:

x4 Infantry Beam Weapon Armor
x4 Infantry Beam Weapon Damage
x3 Infantry Beam Weapon Ranged

x2 Vehicle Explosive Weapon Armor
x2 Vehicle Explosive Weapon Damage
x1 Vehicle Explosive Weapon Ranged

x1 Tank Concussive Weapon Armor
x1 Tank Concussive Weapon Damage
x1 Tank Concussive Weapon Ranged

I don't like to do it that way, only because I want the "whole package" when I attack with just one squad. I don't mind the keeping track of- I'm the type of person who can keep track of things well. And what's with the 0 damage?

I would recomend less or no damadge units they are good near the start but after that they can be beaten easily, just by being outranged with not as much life as the armour class

So will this work:

x5 Infantry Beam Weapon Armor
x2 Infantry Beam Weapon Damage
x4 Infantry Beam Weapon Ranged

x2 Vehicle Explosive Weapon Armor
x1 Vehicle Explosive Weapon Damage
x2 Vehicle Explosive Weapon Ranged

x2 Tank Concussive Weapon Armor
x0 Tank Concussive Weapon Damage
x1 Tank Concussive Weapon Ranged

your hurting yourself by having any damage units i takes 4 turns (most battles are over in 1 or 2 turns) in order for them to do more damage than a range unit so if you can afford them range armor is the way to go

Okay then.

x5 Infantry Beam Weapon Armor
x4 Infantry Beam Weapon Ranged

x3 Vehicle Explosive Weapon Armor
x3 Vehicle Explosive Weapon Ranged

x2 Tank Concussive Weapon Armor
x1 Tank Concussive Weapon Ranged

or should I flip the armor and ranged values?

Hah, my leader on Earth 3 had it wrong. He suggested 40% damage+armor, 20% ranged. Dang, I overloaded on damage units.

stick to ratios around this

8/22 infantry
5/10 vehicles
3/7 tanks
