You're correct - I used the SPWWII LCM6 icon as a base for the ATC. I scaled the exisiting Monitor Icon so it was the same size as the LCM6, then did a bit of cutting and pasting to incorporate the LCM's well deck with the Monitor to get the ATC. I replaced the old Monitor Icon with the scaled up one to keep the ATC and Monitor to scale with each other. The CCB is simply the scaled up monitor with the mortar pit & canvas cover removed and decked over.
"I guess the next question is could I use these in my pack?"
Thanks, you'll be credited of course. I also took the liberty of adding the cover for the cargo area from my icon to yours to create more of an effect like seen here.
The PBR Mk. II was normally armed with twin M2 .50 Cal HMG in a forward turret, a single M2 .50 Cal HMG pintle mounted aft, and either one Mk 18 40mm AGL and one M60 7.62mm MMG or two M60 7.62mm MMG amidships.
I mean - which programme do you guys use to create these icons and what are the parameters (size, etc)? Sorry for that question, has probably been asked many times - I might have overlooked it.
