In most cases this kit is a worse Rifleman and in some cases is literally a Rifleman without an ammo bag and therefore completely pointless. If it is the case that this kit will remain present for conventional factions then a simple loadout modification might potentially improve its specified utility.
Move to Fire Support section because it would likely be too powerful as a basic Direct Combat kit.
Retain CQC orientated weapon, (full-auto, red dot only).
Give access to a Ladder and 10x Frag, 6x Smoke grenades.
This emphasises the CQC Specialist aspect of the class with Frag and Smoke spam to offer versatility offensively/defensively, and access to a ladder which gives the squad/team more options in terms of mobility and verticality. This would in-practice function like a Grenadier/Rifleman hybrid that excels under 50m. This change heavily emphasises the kit's intended role instead of being ''A Rifleman with no ammo bag and like maybe an extra grenade lol''.
Otherwise I see little value this kit offers a squad compared to other options. Honestly any ideas here would be appreciated.
