Well it is work-in-progress but I can't seem to find the Edit button anymore. How does that work on this forum? On other forums you can always edit your posts but you seem to lose that ability after some time.

how are you going to account for an enemy bunker, razorwire over the southern entrance, enemies spamming grenadier grenades and RPGs off the Southern roof, or enemy marksmen/snipers covering the Western walls?

Smoke should keep the enemy from seeing you. Covering fire by the support group should keep their heads down. Remember that when you assault you pick the time, so it should be you who has first sight on the enemy. Especially with this flag where there aren't that many places where the enemy can be. Grenades are tough yes, but the attackers have a far smaller area to grenade than the defenders.

But this post is more meant to show a principle. Smoke to block line of sight to isolate certain areas/enemies. Assign people to certain sectors/jobs to keep covering fire and attack the enemy from multiple enemies. And setting objectives. The backyard is taken first then all fireteams attack the western building. Do not get distracted by the courtyard, throw more smoke if you are. The courtyard should then easily be cleared from the western building. Northern building can be cleared while keeping a foothold on west. By holding west you have secured a line of supply while cutting off the one from the enemy.

Plus if you do it well you should have spotted a bunker before assaulting and that would require a different plan. Multiple situations, multiple solutions. This is just one of them.

When I defend hilltop I place a bunker in the middle. Place razorwire at the front entrance to hinder infantry, sandbags to stop vehicles coming in. The back entrance can be completely blocked by one well placed sandbag. You only need to fear grappling hooks. Defending is dead easy. Luckily the militia don't seem to be organised so good when I am British.

Hilltop is one of my favourite spots in the game. It is a small area that can be defended by one squad and allows for lines of approach.
