newbie question about scale and rivers

[Warsaw Bill]

Hello all,

I'm starting to create a scenario built around the defense of the Suwalki corridor (read here for more).

One of the first engagements will be a Polish / American delay vs Russian advance near the Pasleka river (here).

Question 1: Just to confirm, 1 hex equals 50 meters. Correct?

Question 2: it looks like the Pasleka river is between 18 to 30 meters wide. I want to model this accurately enough. Would this be a normal water hex or a stream hex? I think it should be a water hex, because a stream hex could be easily crossed, whilst a water hex cannot.

Question 3: Tactics. The largest Polish town near the Suwalki gap is Elblag. The Pasleka river is the largest (widest) river between Kalingrad border and Poland. There is a major highway (S22 / E28) which leads directly to Elblag. I'm thinking the Russians would send a very large reinforced convoy towards Elblag (probably in conjunction with a large airborne assault on the small city).

The scenario I'm working on is at the bridge that crosses the Pasleka river. The Polish and American forces must stop / slow this convoy.

I'm imagining the Russians might insert a special forces group in and around the bridge prior to convoy vehicles crossing. I'm also thinking there would be helicopter escorts and a ton of Russian air cover. I'm thinking the Polish and American forces would be light and fast anti-vehicle units. Is shoot-and-scoot still a used tactic? The area is heavily forested, so it kind of makes sense as a place for an ambush.
