Wearable Multi-gun platform for versatile personal offensive/defensive operations.
As weaponry developed throughout the Interplanetary and Nanotech Ages military equipment became far more specialised. Typical campaigns would be fought in and on sea, land and air (and later subterranean, space and cyberspace) with a huge variety of tactical situations. Armies became highly specialised organisms prioritising communication and tactical oversight to be as effective as possible. As specialisation grew the logistical, tactical and strategic challenges grew exponentially. Increasingly sophisticated military AIs were developed but these could only help so far, entire battles could be quickly lost as the enemy destroyed a critical asset resulting in a quick succession of defeats of units now lacking the necessary support.
To counter this various nations and corporations began R&D projects focusing on increasing the capabilities of individual soldiers (though various transapients used bizarre chaotic tactics to make increasingly complex yet increasingly stronger armies). This lead to a spate of multi-role training and weaponry, one of the most significant developments was that of the Combat Jacket. Resembling a thick hooded coat a Combat Jacket (CJ) is composed of an outer layer of reactive armour weave protecting an inner layer of programmable gel fibres. Within the inner layer a suite of weaponry is to be found that can quickly be moved about the jacket by the gel fibres before being deployed on telescopic, fully prehensile tendrils through orifices that can be formed at any point along the outer layer. The loadout of CJs can vary greatly, below is an example of a typical balanced suite from the early First Federation era:
To operate a CJ soldiers had to undergo extensive training to deal with the increased tactical know-how of using so many different weapons all at the same time. Many soldiers failed CJ training programs without extensive intelligent augmentation via military DNIs that granted increased multitasking capability as well as causing a synergistic fusion of the soldier and on-board tactical AI during combat.
Whilst CJs offered a great advance in infantry tactics they found themselves constantly in competition with ever increasingly sophisticated mechs (including wearable exosuits) and cyborgs, both far better platforms for multi-weapon loadouts by including them in artificial/augmented minds/bodies that are fit-for-purpose. In addition super-specialised armies formed by transapients that seem to be immune to the perils of modosophont specialisation, indeed taking out a critical asset will just cause a protean change strengthening the army against further attack.
The development of utility fog based swarm weapons such as Active Polymorphic Defences were the nail in the coffin for CJs and indeed almost all modosophont infantry. Having said this throughout history CJs have seen use in various wars in midtech civilisations and still are favoured in many societies for personal defence and/or sporting reasons.
With multi-function ammunition: capable of assuming a variety of shapes for armour piercing or antipersonnel. Contains fluid which can be quickly modified by in-built nanomechanisms to assume a variety of toxins or become highly explosive.
Launched from a rack before deploying to ornithopter mode with rocket booster: capable of adjustable explosion as well as proximity fuse and remote detonation.
Ablative Armour - Text by M. Alan Kazlev Any armour that protects against beam or HE weapons by ablating, or vapourizing, as it is hit, dissipating the destructive effect of the weapon. Because ablative armour is soon eroded it is not much use in a sustained firefight. Includes soft, hard, laminated, reactive, and smart ablatives.
Armour - Text by M. Alan Kazlev  A defensive covering, as of adamant, arachnoweave, kevlar, metal, wood, or leather, worn to protect the body against weapons (see also Body Armour).  A tough, protective covering, such as the chitinous exoskeleton or carapace or bony scales covering certain animals, dermoplasts and armoplasts of certain neogens, or the metallic plates on tanks or warships or shielding or laminated passive or active armour of a fighter or a starship.  The combat arm that deploys armoured vehicles, such as tanks or Mecha, or the individual units and armoured vehicles.  A blue or khaki goo shield.
Janusoptic - Text by M. Alan Kazlev Photonanotech transceivers utilising Optical Phased Array technology to allow invisibility and other optical effects. Specialised interlinked mesobots and nanobots enable both reception and transmission of photons. As well as being widely used in stealthware it is also a potent laser, although this also depends on energy storage and capacity
