Beyond target: The West is open, that's a fireball cover bold, clip a cord to it inside, countersink. Hidden Counter measures West to surprise Paratroopers, tempting. Aiming a Warhead West is better than a direct hit & off centre.
If one has been hit dig a hole & scrape first, then put in a front row. Start building every twenty minutes regardless if they are being knocked hard. Ask Westminster how to move large stones. Pull my special sheet over the fork lift. Repair fake forts with hot blocks. Keep putting tents up nearby. Drive a JCB around every few minutes. This Fort is mainly to protect the heavy weapon & ammo, or the hole would be alright alone.
Choppers lift heavier blocks. They need to be in the air a lot of the time until dark. Keep them busy.
