Your quite welcome Para. It is starting to come back to me the more I delve into the forums and my old CMBB maps and scenarios.
I agree completely on the 2 up, 1 back tactic as well. It is how I play at every level from fire team to Battalion.
You want fresh reserves, not scraped-up leavings and rattled ammo bearers.
Since this was a defensive battle, here is my personal thoughts on possible improvements. Hindsight is 20/20 and all that. Again, no judgement on our esteemed host should be implied. I am WEGO, and he is RT. he knows better how it goes in that world. He also made the brave choice of no armor.
Mobile A/T assets. In any defensive battle, one may wish for a "fire brigade" unit that can help, then move quickly to help somewhere else. In the WWII world we all about to embark(or re-embark) on, this means a high-velocity 75mm gun carried by a tracked vehicle. Even if it is a single tank, it can make the difference.
Use all your assets. If you get a truck, keep it somewhere out of sight, but close enough for transport and ammo supply duties.
Artillery has been and always will be the sharpest teeth of any military formation. Buy the best you can possibly squeeze into your budget. I would personally rather have a dozen well-aimed rounds of 120mm mortar fire than another platoon. Kill the enemy's morale before he even gets close and the battle is half-won.
Look for and exploit keyholes. That wonderful LOS that goes past trees and between two buildings to the most likely entrance to the objective. Find a way to make the enemy stop/slow there so the long-range asset can take the shot. Wire FTW.
Recon. Each flank gets a dedicated(read stupid) "volunteer" to go out and look ahead of the lines. Dash to closest cover and hide, then back up and look.
