I still do not believe it’s really Trump doing those posts.
I am sure it’s a least a team and he authorizes. I know the humor is crude, but that seems to be (a) part of the disguise and (b) a way to taunt the enemy.
Trump is many faceted. Remember he hosted or promoted or had some major part in TV wrestling or whatever it is. I read his father had him (and I guess his brother) work in every aspect of building, spent time with all the construction workers doing everything. Construction workers are not noted for their Sunday parlor language.
It’s a war and tough stuff happens in war!
