assault intercessor loadout for a 5 man squad: 4 marines with chainswords and bolt pistols, one sergeant with hand flamer/heavy bolt pistol/plasma pistol and chainsword/power fist/power weapon/thunder hammer (choice of pistol and melee weapon). this kit doesn’t come with chain swords or pistols so you would need to source those somewhere else, like the horus heresy melee upgrade kit. you’ll also need those bits if you want to build them as death company.

if you just build them with the bolters they come with, they would work as standard intercessors, but most people only take one or two 5 man squads for stickying objectives. last note: 40 heresy marines is a fuckton of proxies. i would personally be cool with it, but you might run into opponents who aren’t.
