The China War (SPI/Strategy & Tactics 76, 1979)
Scenario Two: Objective: Hanoi! After-Action Report
The second of three scenarios in SPI’s The China War, Objective: Hanoi! covers a hypothetical Chinese attack on Vietnam and Laos in the 1980s, designed to preemptively prevent potential Vietnamese intervention in a wider Sino-Soviet conflict. The scenario lasts for ten turns, each of a week, with both players receiving Victory Points for eliminating enemy units and controlling six hexes, mostly large cities. The Vietnamese side controls all six victory hexes at game start, giving them an initial 57 VP advantage.
No optional rules are used, and the rules-as-written guide play, meaning that the barest sliver of mountain in a hex turns the entire hex into a mountain hex, with commensurate penalties for movement, combat, and stacking. In effect, the entire Sino-Vietnamese and Sino-Laotian border becomes ringed with mountains. Suggested house rules—basically boiling down to appeals to common sense—would use predominant terrain, or crossed-hexside terrain, as determinant, but the rules-as-written hold sway in this playing.
Objective: Hanoi! features fewer than twenty units on the Chinese side and a scant eight on the combined Vietnamese/Laotian side. Almost all of these units are corps/army in size. While the Chinese player can break down armies into three divisions each, the Vietnamese player cannot do so, almost certainly due to countermix limitations rather than any real-world tactical inability. As a result, the initial Vietnamese setup cannot cover all possible avenues of approach. Combined with the game system’s lack of zones of control, the Chinese will make headway somewhere right from the start.
I opt to place the strongest Vietnamese unit, a Mechanized corps, in Hanoi as a mobile reserve, with three Infantry corps lining the eastern border, from Haiphong through Cao Bang. The mountainous northern approach remains open. On the Laotian front, a Vietnamese Infantry corps sits in Dien Bien Phu, with the three weak Laotian Infantry divisions screening Vientiane.
Stacking limits in mountain hexes, three divisions or one army/corps, severely restrict the Chinese ability to mass firepower, so the main invasion thrust, some eleven first- and second-line PLA Infantry armies, will be directly towards Hanoi from the open region near Nanning. A “flying squadron” of two third-line PLA Infantry armies, backed by a lone Armored division and an Airborne division that can’t actually airdrop, will attempt to race in from Kunming in the north, hoping to encircle Hanoi from the west. The remainder of the Chinese forces set up to attack Laos, but the strong Vietnamese unit in Dien Bien Phu poses a threat to an already precarious supply line on that front. They may need to initiate another siege in that famous village.
