This a follow up on the previous post that asked how strong graphene armor would be and the general conclusion is that we have no idea sadly. So in this post I will ask a more relevant question.
If we have made armor with advanced, light-weight carbon and ceramic based materials that can easily stop most bullets like 9mm and 5.56mm calibers that are used in military's and cover the majority of the human body. How does this affect infantry warfare and more specifically guns?
Will guns need to get bigger and stronger to compete, or something else entirely?
And for those who will point out that modern militaries do not cover the entirety of their soldier's body in armor due to weight, heat and comfort issues: Let's just say that the same advancements that made the armor in the first place also allowed the creation of cooling load bearing systems that are simple and rugged enough to be used in the field.
EDIT: I fixed the question and want to clarify on the "entirety" part: What I meant to say was that the soldier has more armor on person than modern militaries to protect the extremities, which is allowed by the lightweight nature of the carbon materials, the cooling capacities and 'minimal; load bearing systems. Meaning that there are gaps in the armour, albeit covered in a cloth that has carbon materials like CNT.
Sorry for any confusion.
