Questions from my first scenario...

[ComradeP]

Now about campaigns - I can't find a campaign in my Stalingrad '42 folder. In Combat Mission a campaign is a series of linked battles where you import your units from one battle to the next. A scenario is one battle. Is it different here? All of my files end with the .scn tag.

Ah, yes, apologies for not being more clear on that point: I'm referring to the largest scenario(s) in the game as the "campaign". Some games cover one campaign, others cover several.

As Lohengrin wrote, the assault rating for units that can't assault is mostly there to increase the survivability of the unit when it is assaulted itself, as the outcome of the assault comes from a comparison of assault strength and defensive strength, which is then adjusted to the low/high loss values for assaults in the parameter data dialog. Unlike in the majority of wargames, odds are essentially meaningless here and have no direct effect on the outcome of an assault.

Note that assaults are resolved for an entire stack at all times, not for single units, so if you stack a unit without an assault value (like an HQ) with a unit with an assault value (which usually comes down to everything except HQ's) the HQ's will contribute their defensive strength normally.

It's a risky strategy, but it can be worth it to stack an HQ that you're either going to lose anyway or that isn't immediately needed elsewhere with defenders in a crucial hex. The bigger the HQ, the more useful this becomes. In PzC, the tactic is however less useful than in Panzer Battles as HQ's are significantly smaller in terms of the number of men in the units compared to the standard infantry unit size (battalion) in PzC.
