Man - this game punishes the stupid!
I just moved my 1st Platoon onto a card with a spotter - confident that I'd be able to get him with a grenade attack. Unfortunately, although the grenade attack was successful, during his event phase he vacated the card and the grenade turned into a miss. -2 (exposed) and -1 (grenade miss) and +2 terrain gave a -1 NCM
Platoon CO is down, 1st squad suffered a casualty and a litter team, 2nd squad suffered a casualty, 3rd squad was pinned, mortar was fine, bazooka was pinned and MG was a casualty.
I was so focused on getting him away so I could move forward, I forgot about the danger of a missed grenade attack on exposed units
