Don't upgrade them with G43s. The difference isn't big enough to warrant that.  The advantage is they require no build time early on, are cheap/effective, and they see kind of like snipers.  All munitions upgrades go to the first 3 x panzershrecks.

I like FJ's surprise ability but they are so, so expensive to reinforce and to lose.
Panzerfusiliers + Volksgrens with Panzershreck is a good duo to use at least against the USA.
