Dry-fire, dry-fire, dry-fire! Sit your joe's down every drill, have them pull the shooting sticks out of the arms room and then dry-fire practice for 2 hours... Joe will hate your guts but when your team/ squad or platoon is off the zero range in an hour, they will understand. ;)
Every unit NG/RC/AD all have access to Laser Marksmanship Training System (LMTS) equipment “the beam hit stuff“. All you have to do is request it for every drill, you may only get it once or twice a quarter. But that better then nothing. The LMTS stuff helps with the dry-fire practice, by giving joe some feed back.
Also you can request training from NGB Marksmanship Training Unit (MTU) They do SDM and master gunner courses for the NG. They conduct these courses at Camp Robinson AR, or they will send a Mobil Training Team (MTT) to your unit if you have enough people attending training.
Also send your jr NCO’s or senior E4’s to the shooting competition’s, local state matches, AFSAM, Wilson cup, All Army and any and everything else. Those guys will bring the best marksmanship skill back to your unit and once the other joe’s start watching them getting EIC badges and marksmanship tab’s. The rest will want to compete next year. But this time you will have solid jr’s in place to train the next batch of shooters, as well as running PMI for the unit.
Also talk to your leadership about buying .22cal conversion kits for the unit rifles, this will allow the unit to train more on marksmanship at a much lower cost. Even if you only get 20 kits, you can rotate your unit through them and allow marksmanship to become a priority again…
If you need some help in finding info or NSN for equipment, or even tracking down resources in you state. Let me know and I can normally get the info fairly fast. I have friends at AMU, SARG and MTU and they all jump at a chance to help train a unit in marksmanship…
Either way good luck ;)
