I completed the first chapter. The fire power is insane.
In the Sci-fi version of the "Things they carried" Mr. Rico was armed with...
Hand Flamer
"Mini" <2 Kilo Ton Nuclear RPG with 3 reloads. A shoulder fired weapon that was brought into firing position and had a trigger that was squeezed.
Backpack Grenade Launcher (Y-Rack). It could be reloaded.
Heavy Flamer
Hand tossed "grenades" on the belt. Including the infamous "I am a thirty second bomb..."
"Fire Pills". light explosives tosses in bundles
A knife Beam to cut away a wall section
and yes the jump jets
As a note except for the Y-rack none of the weapons were "mounted" to the suit. I would love to see an artist recreate all that.
I can draw only one conclusion.

Have fun in the discussion you Apes!
