Guns on fighters?

But to answer the question- As an aside, what are the thoughts of those who
have been in combat?
Are
guns
on board nostalga, or, are they a practical weapon? BRBR

Not been in combat but the onboard gun is a reliable and cheap weapon that is
essential if you find yourself close to your adversary or if you are armed A-A
only weapons-wise and you need to do some damage on the ground.
