Add the ability to customize you vest and what is on your vest( would love it to be like contractor exfilzone ) with this add mag pouches and backpacks to be able to store items for you to use in battle like rpg ammo or more mags add a meg pouch to attach to you vest and whenever you interact it will show a bandage, saline, and a medical syringe
Radio system
To talk to your team you will have to have a radio you can add a radio pouch to your vest if it is in your vest pouch you can hear your team or while in your hands to talk to your team you will have to grab the radio then talk
How kit customization Would work
When you first join the lobby a menu will come up and you can click parts of the body and a list will appear and show the available vests, backpacks, and something I have never seen before a tack belt once you select whatever you put on if it is a vest, tac belt once, or helmet you could customize-it will show just the item you are customizing a list will show up showing your available pouches and you can drag them to a the vest/ belt with the helmet you can select different night visions
I think milsim like scenarios would be great with a physics based game like this
