History Line: 1914-1918/Ratio

With less units, less factories and a ridiculous resources income, I found the only way to win this battle was to "steal" units from the enemy, Sun-Tsi and all that.

Prerequisites

 * Wait with capturing the depot until the enemy moved in, to receive free units.
 * Repeat this whenever he wants to capture your depot or factory (don't forget to put infanterists as guards next to each)
 * Use the construction unit to block the path from the south to the depot (just build for 1 round, not construct the full depot). Also build one of these half-done-depots in the north, to block units from moving towards the northeast factory.
 * Build 1 pioneer unit to change the trenches at my headquarter. The way to the west needs to be free, but blocked to the south, between the mountain and your HQ.
 * Don't build planes, they're too expensive, and this allows you to ignore the enemy's AA-units.

Steps

 * 1) Leave light artillery and some Elite Infantery to guard the HQ
 * 2) After collecting enough units (only build Elite Infantery because of the planes), I moved to the north-west factory with all I had.
 * 3) Build Armoured Cars and repair units, then move as fast as you can.
 * 4) Capture the HQ.
