History Line: 1914-1918/Order

Strategy
It is a big map but is in fact a no-brainer. Fall back and repel enemy assaults on each of your facilities while constantly repairing your damaged units. Direct your aircraft squadron in the south against the approaching enemy cavalry for target practice to gain experience, then move the aircraft to various hotspots. Use aircraft to prepare the assault on the enemy factory north of your HQ, and on the depot and the factory on the western river bank. Capture them one by one. Ignore the patrol boats, they are no threat, just stay away from the river bank. Place aircraft units on the bridges to the north and east of the central depot in order to prevent enemy units from crossing, and use the time for repairs. Oddly, you will not be able to produce new aircraft, so make sure to keep the existing ones in good repair; produce heavy and light artillery instead, which you can deploy quickly from newly built trucks for the final offensive. After capturing the factory north of your HQ, keep an eye on enemy units trying to sneak through to your HQ: keep a small mobile defense force in the rear. For the final showdown, build up massive battle groups with tanks and artillery on trucks. Let your aircraft interdict enemy bunkers and artillery, deploy your heavy and other artillery close to the river, and let your tank columns cross the bridges into the enemy HQ area from the west and south.
