Even the Romans felt the tensions.  Consider a scene in which Big A and the PEO CART (Chariot Acquisition for Roman Triumph) are choosing between acquiring 100 extra battle chariots or establishing adequate skills, parts, and facilities to establish a "full up" and functioning chariot repair line at Rome Logistics Depot (RLD) to be ready at the battle chariot's Initial Operating Capability (IOC) date.  Meanwhile, system engineers in Florence have sent word that they've made some design tradeoffs and selected battle chariot wheel materials that are cheaper than other options, but more difficult to repair in the field and heavier, making transportation more challenging.  The system engineers also propose a revolutionary design feature, the axle.  While quite an innovation, the axle's reliability and repairability are unproven.
