First let's issue the manning. Get more man power.
Second let's issue the fact that 1RCHA is breaking their troops constantly on 105mm towed guns and 155 self-propelled. Now add the fact that the broken numbers will only increase with a towed 155. When all the troops are broken there will be no manning the guns.
Now with the joking aside:
I personally think we should have purchased more light 105's.
In the warfare we're involved in we're dealing with CQB and BUA fighting, a 105 will reduce collateral damage to ssurrounding"non-combatants" and "non-military tgts". There are several light guns out there that will come in and out of action fast, with self guiding GPS lay on. This speed is essential in the modern combat, unless on a fire base where tgts are already recorded. Also the air-mobility issue would be resolved...let's face it the LG1 doesn't pack perfect. I remember running trials years ago with CBty when we did the first Air Mobile Op with the darn thing. We had to carry the ammo in one chopper, while the other chopper would carry the gun...not unusual you say! You're right it's not, except for the fact that the gun was stripped of the breach to save on weight and the chopper that carried the gun was stripped of it's doors and would also require to have half a load of fuel to ensure it could lift the weight of the LG1. It's not the guns fault, the choppers we purchased aren't designed for a "war machine", they're executive helicopters painted green. Things aren't as bad now, we only did this to test, and build up from there, however, things aren't great, so we should work with what we have...the choppers are all ready there, now let's look to buying other kit that will work with them, otherwise we will "cripple" ourselves with a bad buy.
I see no reason for a 155. We should be expanding the mobility and speed issues, purchase light guns, and mortars, not just the mortars you "hump", but also some that are mounted.
As for the issue that we may have so much 155mm stock piled: If I'm not mistaken, I believe we fired that off a few years ago when we were told the 109's (155) were being retired.
