He's either a real braggart that's got a few easy kills early on without really having skill... or he's survived more battles than most, and this is his way of saying "I'm a mother f*cking badass. You're screwed".
this is so much FRAKKING win. I really love non-linear sci-fi concepts especially in terms of sci-fi combat and it's various and sundry trappings and mass-acceleration arrays... your work implies some interesting unconventional technological development stories that are fun to guess at.
TOP NOTCH WORK
For this I imagine this hardcore soldier-dude (let's call him whiteCHALK) is part of a Heavy Assault Shock-Force; Mechanized Detachment specializing in 'Lightning-Fast Orbital Drops' and 'Heavy-Point Siege' with a mandate to contain and neutralize heavily armed and armored opposition in urban/semi-urban theaters where collateral damage is a non-issue when compared to Rapid Situation Management.
I imagine whiteCHALK's load-out to be made up of;
1. Body-Suit (sub-shell)
2. Combat-Suit (main-shell)
3. Weapon Systems and Accessories
I imagine a snug (not bondage-tight) suit with two thin layers; An inner layer that monitors his heart rate and breathing, his blood-flow around his whole body, his nerve impulses and injuries and relays this info to a command center where the info is used to help efficiently manage the human resources on the ground. The inner layer also as a thermal fluid circulatory system used to manage whiteCHALK's body heat, and a med-gel circulatory system that in the case of a serious wound can deliver an antiseptic gel that will cleanse the wound, clot the blood-flow to the wound and fill said wound and semi-harden with a fibrous nature, binding the wound futher. It can also deliver a medium strength electrical shock to any specific point on the body for medical purposes.
The outer layer would be a thin layer of emergency ballistic armor and electrical shielding, coupled with a thin carbon-fiber synthetic auto-muscular system that aids in whiteCHALK moving the bulky Combat-Suit with grace and speed.
I imagine that the Combat-suit would offer protection and utility in the form of;
a) Armor composed of ceramic impact plates mounted on woven carbon nano-fiber reinforced polymer scaffolding.
b) Medium level Radiological, Chemical and Biological shielding.
c) Semi-Adaptive Urban camouflage, featuring thin but durable sheets of color changing material on most of the surface area of the Armor, that can take on general ambient/environmental non-complex color schemes. One color per sheet.
d) HELMET featuring AcEl (Acoustic and electromagnetic-spectrum sensory apparatus) tech and a beveled face that mitigates the impact of gunfire from the front. Also atmospheric scrubbing... And it looks scary.
3.WEAPON SYSTEMS CONCEPT
I imagine primary and secondary weapon systems and equipment including;
a) Primary - 4mm variable marksman/assault riffle with adaptive munitions system (ammunition of various types and effects can electronically sync with the rifle's systems) with hardened circuits and electronic firing pin.
b) Secondary - Suppressed 45 cal. firing temperature degrading hybrid alloy rounds (armor piercing but fragment on bodily entry)
c) Equpment - Chalk; 6 pieces of the finest quality.
I would get into even further detail but I am afraid of this getting too ridiculous and tedious, BUT, simply seeing this image sprouted a storm of ideas in my mind,
This is exactly what i always hope with images, that the concept is believable enough that someone can come up with something like this just by looking at it.
For the most part, you're spot on. The only differences in my head are that like most of my other concepts, they wear a rubberised muscle-suit under everything that aids strength and softens impacts, on top of which is a fairly durable and loose combat dress uniform tailored to the environment, tailored to include a load-bearing system of attachments for the hard shell to go on. The hard-shell for these guys is almost a full exo-skeleton to allow them to keep up with mechanised elements, so that the mechs and vehicles don't have to slow down as the infantry can sprint just as fast to keep up the advance. Most of the hard-shell armour can defeat small arms-fire, but the real speciality of this armour is being engineered to also protect from explosive blasts, so even when dropping into a possibly hazardous or pre-prepared battlefield they're fairly safe against anti-infantry mines.
The helmet has ventilation for both the biological needs of the soldier and provides cooling for the entire suit, as well as having a built-in suite of various imaging sensors and communication equipment. The angular design helps maximise protection. In the event of a systems failure the front of the mask can be pulled away to reveal a secondary analogue visor.
At the very end there's a tactical webbing of molle straps for the individual soldier to attach pouches as they need.
