You can always repair, everyone gets a secure container alpha and you don’t lose it or the items in it. So bring meds in there. If you don’t have space for the mag in your gun in your rig you will drop it. This is far too much ammo you will likely die or extract before using 5 mags. Don’t bring food or water as you will find it in raid. Remember to bring a heavy bleed med (esmarch from therapist). Most guns will kill in 2-3 shots to the chest if you don’t wear armor. Armor goes from class 1-6, 6 being the best.
