Hey, Geoff.
I was just laughing at the "Christmas tree as submarine camouflage" in your signature. I was in a CAAT platoon in the Marines (Marinesoldaten) where we drove around in HMMWVs with heavy weapons (.50 cal machine guns, TOWII missile launchers, and MK19 grenade launchers). 15 trucks in 3 sections...very visible, very noisy...but our platoon commander would make us put on camouflage face paint before operations because he said it "puts you in a tactical mindset". We thought it was hilarious and the running joke was that the enemy would see our HMMWVs and not us...like "Oh, my god! There's nobody driving those trucks!!" or "Holy cow! The Americans have trained trees to fight!!"
Anyway, sorry your system grumbles on SH5. It's great escape for me.
