Questions about soldier boy

So these questions have been on my mind for a while. First l, regarding his super amazing energy beam. So, I’m guessing solider boy didn’t always have the beam. I’m the scene where the Cubans are attacked by the reds, solider boy is only seen using his shield and fists to take them out. Also, in noir’s flashback, he isn’t shown trying to use it against payback. And it seems that an anti supe beam would be rather effective in that circumstance. So the question is, what kind of technology do the reds hold that not only allow them to fry the comp v out of people, but also embew a supe with new powers independent of the American compound V. Do you think the reds have their own version, or were they able to modify the V in solider boy’s veins. Secondly, is the public aware of supes being functionally imortal? In season two, Huggies, star, and Mm don’t seem to struggle with the fact that storm front is pushing the hundreds. However, Homelander seems quite shocked to find out how old she is. It seems like the public would know. Consider this, soldier boy is depicted storming the beaches of Normandy in a “documentary.” That would have taken place on June 6th, 1944. Soldier boy was kidnapped in 1984, and seemingly held a major public following for the entirety of the time between those two dates. That’s an exactly 40 year gap, and he didn’t age a single day. Did just nobody notice?
