Searching for Sci-fi novel from the 1980's [duplicate]

Question

I am trying to find a sci-fi novel I read briefly when I was young and waiting in line at a Goodwill. The main subject was about a soldier in power armor fighting a race of lizard like aliens and in the first chapter a soldier near him died after a lizard alien got inside his power armor and ate him. I do not remember the title or author.

I remember the cover seemed to be a desert planet and the soldier in his white or grey power armor walking in a direction and looking slightly behind him. I remember the power armor gave him incredible strength. Any tips are appreciated.

I thought it was Starship Troopers, but I remember the aliens being lizard like or reptilian. The details are vague because this was around 12 years ago, but I distinctly remember that on the power armor, it wasn't a helmet with a visor, but a face mask instead on the helmet. The face mask looked almost like a low poly character design. Lots of angles.

It is not Armor by John Steakley.

Answer 1

Possibly Solar Kill by Charles Ingrid (#1 of 6 of the Sand Wars series)

In the first chapter the Protagonist recalls a rumor

And there were too many stories about altered suits … suits that swallowed a man up and spawned instead some kind of lizard-beastman who was a fighting automaton, a berserker. Rumor had it the Milots were putting eggs into the suits, and the heat and sweat of the suit wearer hatched those eggs and then the parasitic creature devoured its host and burst forth—

Later in the first chapter he does describe a creature bursting out of a suit of a soldier who died in his suit (ran out of power? or supplies?)

And he sees a suit burst open, days after its wearer expired with a horrendous scream, and the armor halted like a useless statue in the pit. He sees the seams pop and an incredible beast plow out, and charge the rim of the pit, taking fully a hundred armed Thrakians with it, even as it bellows. He knows he is dreaming that he has seen a berserker, and tries to ignore the shell-like empty suit left behind in shards, with the crest of Ivanhoe settling into the sand.

Answer 2

It sounds like Bill the Galactic Hero by Harry Harrison. Farm boy Bill is tricked into joining up and ends fighting the lizard like Chingers.

This is a very different and satirical take on the subject to the one Heinlein took in Starship Troopers, it's been described as 'a dramatic summary of all the criticism of Starship Troopers'.
