Mikeg81 said:My experience comes from being with E Bty during 3-06, including Op Medusa. The battery fired about 6800 rounds total of 155 and 81mm during the 6 mos we were there(with about 20 or so of 120mm mortar, but that is another story).
If the tray can't hold the 98 lb HE round on there with out the hydarulics taking a crap, how is it going to cope with a 120 lb MACS round there instead? It seems less of a drills problem and more of a gun problem. The rounds don't rattle around or jump when the gun is fired...
2: One man ram: When one guy is on sentry, one on the gate, two on leave, and two are on GD on the FOB, or out on a convoy, we make do with what manpower we have.
I saw/heard one(that's right, 1) fall back my whole tour, on another gun, in another troop. Non-problem from my experience.
No problem when a round drops short and detonates?
You're kidding right?
The previous roto's Bty commander told me that he had a drop short, and went to the gun postion just in time to see one man ramming. He gave a personal blast of shit to the No 1's and TSM for letting them do it; well deserved but it took that to make them stop.
As for the loading tray, rationalizing something will only get you so far. I'm not sure what round you're talking about that weighs 120lbs, MACS are the modular artillery charge system, none of which weighs that much. But that's beside the point. The system was not designed for it and it begins to break when people do use it that way; what kind of rate of fire do they have then?
I've seen your Bty's comments on AAR's, and other roto's about the trays slowing down and then failing so that they had to be manually pumped with the trunnion pump to lower and raise it, which is exactly what the BAE engineer at Hattiesburg said would start to happen if someone continuously fired with rds on the loading try. The compression and tension caused on the tray by that round he suspected would eventually result in the valves used to set the tray speed to loosen unevenly, causing the malfunction.
Sometime mikeg, I'll show you the high speed video of an M777 firing MAC 5, you'll immediately notice there is quite a bit of movement, and if there were a round on the tray it would be "rattling" quite a bit too. You would be surprised at how much flexing that gun goes through everytime it fires.
BAE is not going to redesign their system for the sake of perceived faster rate of fire when others are able to achieve similar sustained rates of fire without doing that
Here's another example how assumptions can get you in trouble. A certain Bty firing HE in support of a TIC called a SME in the Artillery School wanting to know why they were having so many duds with the new fuse (the guns could be heard firing in the background). Turns out some genius rationalized that the fuse sent for the new WP round should be good for the HE round as well. What this smart guy failed to notice is that unlike the old WP rd that functioned point detonating the new one is an expelling round, and does not use a disruptive fuse, which they should have noticed anyway because of the absence of a booster on the fuse; to wit they were told to stop using that fuse on bursting projectiles. The advice they got, at least in that case, was accepted.
