In "Patrol" each player rolls for Initiative during a game turn using a D20 die.
If you win the initiative roll, you get to activate one soldier or Fire Team.
If you and your opponent roll the same number on a D20, then a Random Event happens.
In our latest game, on the second turn, a Random Event came up and one of the GIs got jumpy and shot one of his own squad mates, that was in the shadows of a building.
It ended up being a Light Wound.
Later in the game another Random Event came up and this time a stray shell fell on a house my troops were sheltering behind.
Krash Boom; there goes almost half of my squad, including the Squad Leader.
That pretty much ended the game for me.
Okay; time to publish this and see what it looks like.
