History Line: 1914-1918/Ratio

With fewer units, fewer factories and a ridiculous resource income, the only way to win this battle is to "steal" units from the enemy, Sun-Tsi and all that.

Prerequisites

 * Wait to capture the depot until the enemy moves 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 one round; do not construct the full depot). Also build one of these half-finished-depots in the north to block units from moving towards the northeast factory.
 * Build one pioneer unit to change the trenches near your headquarters. The way to the west needs to be free, but blocked to the south, between the mountain and your headquarters.
 * Don't build planes because they're too expensive. By sticking to the ground you will be able to ignore all of the enemy's AA-units.

Steps

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