Yeah, relying on the warp is... Well, it's a bad idea. Anyway, a couple of designs
Design: Communications (Vox Casters): With recent events establishing our lack of co-ordination and the enemy's relentlessness the idea of using the humble vox caster as an easy and reliable way of co-ordinating the cult. These relatively simple (compared to warp communication) devices mean that we can communicate over large distances.
Design: Corporate Infiltration: Contrary to most belief, the AdMech does not control all manufacturing of the imperium, only it's shiniest and rarest tech. For the average workers in the hive, and the more mundane and common products they produce, this work is generally left to the owners of the spire's factories (Whom the mechanicus then charges fees to maintain some of the more complex machinery). By infiltrating these corporations not only do we have a secure power base in the manufacturing facilities but a way into the good 'graces' of the spire nobility.
Design: Light Armoured Groundcar 'Tyber':
While the Goliath trucks we have are serviceable, rugged vehicles, they do lack the armaments and armour necessary for frontline combat. The 'Tyber', named after our glorious leader's favourite pet, is designed to fulfil this role. A fast, rugged four-wheel drive chassis that is armoured enough to resist heavy stubber rounds all over while armed with two heavy stubbers in it's turret, the 'Tyber' is designed to be operated by a three-man crew: A driver, gunner and commander/loader. Intended to compliment our trucks, the 'Tyber' provides the fast fire support to the Goliath's transporting capabilities.
