I thought it would be cool to think about what the 3 known/main Factions of We're Alive have in terms of weapons equipment etc. I'll start off with what I think the Eastern Bay "Mallers" have in terms of weapons. Ever since the short but intense battle for the Tower we know the "Mallers" have lost roughly half of their initial numbers before the assault on the Tower, with that slight loss of man power (I say slight because the "Mallers" Are apparently building their ranks again via found survivors. I don't think every survivor they find instantly becomes a slave but I also think that the process of choosing which of the new survivors become slaves and who becomes a "Maller" is all that complicated. I wouldn't be surprised if they were going by the 'Eeny, meeny, miny, moe' system to be honest. My backup for this theory is that there is a female "Maller" other than Scratch, in part 2 of chapter 21 When the Scratch's convoy makes the last stop before the Arena Shes introduced talking about "Sam" being ripped out of his seat during the ambush. She remains nameless but his is still important.) they have also lost a significant amount of weapons and ammo. I'm fairly sure that at this point in the story the "Mallers" have found a significant amount of weapons and ammo stolen from other survivors, scavenged by scouts and what not I doubt they have enough to fight another war but I'm sure they have more. Thinking about burt's shop and possibly the military base and any other locations known or unknown, the "Mallers" probably have in terms of types of weapons mostly pistols and handguns of a common caliber (.45, 9mm, .22, .38 etc.) Common civilian models and variants of Rifles (AR's, various types of hunting rifles, semi-automatic burst fire and single shot rifles with the firing pins removed for full auto capability.) Maybe an assortment of SMG's and shotguns too.
The Colony's "Guardians" are apparently (or were) the only group within The Colony that stayed armed 24/7 (most likely to keep the laborers afraid to step out of line.) Micheal described them as all having rifles with scopes slung around their backs. The "Scavengers" most likely carry smaller firearms such as pistols and sub machine guns. The "Super Marjent's" call the "Guardians" when they feel the use of firearms maybe needed apparently, We have only heard the "Super Marjent's" using what I assume is a cattle prod. Ever since the team of 3 and the new Tower resident fought their way out of the The Colony taking most of The Colony's ammo reserve with them. They most likely only have the ammo left in their guns and nothing more.
And we all know what the Tower Residence have at their disposal by now I'm sure so I wont get to far into that. But I will give you what I assume the rest of the Tower Residents have (not the main characters.) The guns they took from dead "Mallers" during the siege on the Tower, the rest of the weapons from burt's shop, the Rifles and machine guns from Burt's "real safe".
That is all Ladies and Gents!
