only 3 artillery i would love to have...in 1/72 scale:
1. 155mm M777 howitzer...with movable bits so it can be displayed as-towed or blasting-away.
2. MLRS...m270 self propelled loader/launcher
3. dragon 120mm mortar (or is that all ready on a LAV?
maybe a 4th...HIMARS
nb. these are all nice to support usmc modern infantry battalion...i'm trying to build up a Marine Expeditionary Unit with all the bells and whistles. these kits would certainly help.
