The official description identifies Finest Hour as an RTS with WW1, WW2, Cold War and Modern Day start dates. It also names missions, encirclements, supply, division design and battle mechanics.
Start by identifying the era and country. Do not assume borders, missions or available technology are identical between start dates; a complete scenario matrix is not available in the checked public metadata.
WW2 Germany footage reports research, equipment and building production, idle factories and current divisions near the start of the match. Source: OFhUN8_Dkrw@00:28-00:48.

The same footage shows civilian-factory construction, equipment production and division training as separate tasks between OFhUN8_Dkrw@01:13 and @01:58. Treating them as separate queues is an observation; the optimal ratio between them is unavailable.
Avoid copying a fixed factory or division count from one video. Those values can depend on country, era, resources and game version.
Germany gameplay assigns divisions to an offensive front at OFhUN8_Dkrw@01:13-01:18. The official roadmap separately says drawable front lines are planned so divisions behave more intelligently. That roadmap wording means front-line behavior may change after this guide's review date.

Supply and encirclements are named by the official description. France footage shows players creating and reacting to encirclements, including jQxwDL3wkv4@03:04-03:36 and @05:46-05:58.
The checked sources do not provide exact supply or encirclement modifiers. Use the map feedback visible in your current match and do not rely on unsourced percentages.
Before treating a tactic as current, compare the Roblox updated timestamp, selected start date, country and game version. If one of those changes, label the recommendation as needing a recheck rather than silently carrying it forward.
