Ah starship troopers was a good fun take on alien war...
Heinlein did a fun job with it...

But frankly....
up among one of the best ....right up there with what is considered the finest and studied in military actually is the "Forever War" books.
Dealing with the ramifications of fighting a civilization a vast distance away...
and what both civilizations go through in the process...
Very very well done.

Another truly truly good read is "Armor" by John Steakley


If you want fighting alien "bug" civilizations...
It beats Starship Troopers ...it beats many military scifi ....cold.
It is in my Top 10 of military scifi.
It is just that good.

It doesn't just deal with the fight...the logistics of war on planets that have little to no atmosphere for humans...

It also deals with the politics of war and military, the madness of a military structure that doesn't understand exactly what the issues on the ground are.....and the psychological ramifications...
The tech involved...in the plot...the individuals in question involved that gravitate around the central figure of one man...
all of it effectively in writing style puts your head...in one of those suits...looking out...dealing with it all...
The effect is exceptionally well done.

A movie of this book would take the box office .

I reread it once every couple of years...
It is one of "those" kind of good reads...
I also have the audio book ...not as good as reading it though.
