Best CG games that fit this description...

[Vic Provost]

This is easy...

Hands down, The CG which probably best fits your specifications is the Operation Turnscrew CG which is included with Dispatches From the Bunker #44.
Designed by Tom Morin, the CG depicts the late 1944 assault on Rees, Germany by British forces. Although the battle occurs in a city on the Rhine River, there are no amphibious landings, river crossings, airborne landings, etc. There are vehicles in this, but not an excessive number or complex assortment. There are 5 stand alone scenarios for this action, in addition to the CG. Also included are designers notes and another excellent article by Carl Nogueira I thoroughly enjoyed playing this one, and I recommend it very highly.
Another typically excellent, well play tested product from the Bunker crew.

If interested and not a subscriber, get a hold of me, Vic (publisher of Dispatches from the Bunker) at: aslbunker@aol.com

I'll get you the info you need when you do. You can also check my monthly update in the Emporium link here at Game Squad.

Tom took a scenario I originally designed for On All Fronts in the 80s and did some research to truly flesh out what happened there with a beautiful HASL map, 5 scenarios and a manageable campaign. We did have a blast in playtest, the British have a slight edge but the Germans will not give up that town easily. Let me know if interested and I'll hook you up, Vic.

I immediately went to Ozereyka Bay too. Not too many vehicles, short, interesting situation with naval OBA, aircraft and axis minors.

Yup, Ozerekya Bay by Lone Canuck. I’ve played it three times. Very few vehicles, no night, simple campaign rules. About as straightforward as it gets.

Another vote for Ozerekya Bay. Great fun and very straightforward both sides attack and defend and good mix of elite and standard units.

 

[volgaG68]

Yet another vote for OzB, and can recommend RftM by LCP as well. IIRC, a handful of ACs and motorcycles is as vehicle-y as it gets.

 

[Paul John]

Another vote for Ozerekya Bay.

Do y'all mean Ozerekya Breakout?
