Historical Advanced Squad Leader (HASL) are additional modules for the tactical wargame Advanced Squad Leader intended to depict historical events using maps produced from terrain maps, and featuring linked scenarios called Campaign Games.
The Campaign Game (abbreviated CG throughout the rules and hereafter) allows for a wide variety of situations and nearly limitless possibilities.
This will usually result in wild jagged lines penetrating into enemy held areas which show where your last major effort was made...After each campaign day in which at least one side had decided to go on the offensive, each day varies from a minimum of five (game) turns to an infinite amount (though likely less than eight)...both sides (then) refit and redeploy anywhere along their defined perimeter...
If both sides are Idle, then a game day passes without being played out...(either way, at day's end) both sides again go through the Refit Phase...The Refit Phase features events like promotion, extinguishing blazes, AFV machine gun exchange and scrounging (as well as purchasing fresh forces with CPP and FPP).
Red Barricades: Squads at the Gates: Advanced Squad Leader does Stalingrad by Tom Zlizewski Fire & Movement: The Forum of Conflict Simulation, August 1990 (Number 67) Perhaps the only perceived drawback to the historical modules was a lessened re-playability.
However, the dynamics of the campaign games guaranteed that no two CG would play out the same, even with the use of similar forces and identical terrain.
Red Barricades (RB) was released in 1989 and focused on the fighting for the Krasnaya Barrikady ordnance factory complex in Stalingrad.
Special additions for this module include rules for new terrain types including debris, railway embankments, culverts, storage tanks, single hex two-story buildings, and modified rules for gullies, factories and cellars.
As well, two new weapons (the Soviet Molotov cocktail projector, also known to Combat Mission players as an ampulomet) and the German StuIG (a 150mm infantry gun on a Panzer III chassis) are introduced.
Kampfgruppe Peiper I (1993) is the first of a two part module, focusing on the fighting by one of the SS armoured spearheads in the Battle of the Bulge in December 1944.
Acting as a companion to the KGP I module, it depicts the fighting between Waffen SS forces of Battle Group Peiper near the Belgian villages of Cheneux and La Gleize.
Additionally, Day 7 of the Chapter K training module is included (later released with the second version of the ASL Rulebook).
Blood Reef: Tarawa (1999) depicts the landings at Betio Atoll in 1943 by United States Marines.
The scenarios all feature British and Canadian forces during Operation Veritable, the battles to clear the last German holdouts west of the Rhine, to the east of the Nijmegen Salient, as a preparation for the 21st Army Group's crossing of the Rhine River in March 1945.
It covers the fighting in Stalingrad during September 1942 near the Central Railway Station and includes several famous historical locations such as Pavlov's House and the Univermag Department Store where General Paulus had his headquarters at the time of the surrender in February 1943.
It covers the fighting near Strasbourg in December 1944 between the American 7th Army and German 21st Panzer Division and 25th Panzergrenadier during operation Nordwind.
These capture the portion of the battle where an intense combined-arms struggle between a few handfuls of infantry companies and tank platoons of both sides played out on a daily basis in this small French village.
The HASL module 10 Red Factories (RF) was published in January 2019, designed by Charles Kibler.
Red October covers fighting at the adjacent 'Krasny Oktyabr' factory complex in Stalingrad in late 1942.
The islands, garrison, and attack forces were small enough to be represented in their entirety in ASL format for this feature.
ASL Annual '97 includes a mini HASL game which consists of a fold out map, Campaign article and 4 scenarios.
ASL Journal #2 presents a Kakazu Ridge historical study which includes a full-sized HASL map, scenarios, counters and articles.
ASL Journal #6, released in 2005, offers a Primosole Bridge HASL feature with Rulebook Chapter, campaign games and historical map insert.
