If you can't join them.....

Blue base
About an hour after the ambush of the invading marines
"Hey, Steve, over here" whispered Zack as Steev dragged in another
glowering marine, covered in paint.
"I've just got a coded message from Kayn"
While Druscilla and her squad were rounding upo the remains of the
Marines who had survived the ambush, Zack had been left in control of
the com. The few security agents left guarding the base could barely
operate a microwave, and if Steev had been let anywhere near the
radio, he would have already cannibalised it for parts, so Zack was
the only person left.
"Apparently a group of marines are going to use the weathertry to
colour the rain green!"
"What?! The cheating, filthy, impotent, low life scumbags!!"fumed
Steev.
"Yeah, I wish I'd thought of it first as well. Not to worry, I've
got a few tricks left up my sleeve." Zack rumaged around in his
backsack, and pulled out two strangely shiny coats.
"I've treated these with a special non-drying paint solvent. Look
how paint just runs off it. I've only got two, but I've got another
cunning plan which might just win us the day..... However, I'm gonna
need your help."
The two sat down, and were soon busy discussing air speeds, thrust to
mass rtatios, and scatter patterns......
