Woulod it be caused by the guy lugging the heaviest weapon is the last to arrive so is modeled to stand at the back? Had the same problem with some of the larger teams modded in cc3, the guy with the Pzsk was always stooging around the back.
It is, but it is a data file induced problem. The heavy weapon tail end Charlie's in team movement is due to the Weight column of the Soldier.txt file. Almost always, that has a common figure of 40 pounds of kit for every weapons combo. That column is only for kit and does not include the weapon and ammunition weight, which is assigned from the Weapons.txt file. A BAR, Bren or MG34 gunner ends up carrying the heavier weapon and all its ammo as well as the 40 pounds worth of helmet and kit. Both the Soldier.txt Weight and Weapons.txt Weight columns factor in to the fatigue calculations for each sprite, making for one tired and fatigued puppy by the time he catches up to the other, now rested, members of his team.
To fix that, weapons combo's in the Soldier.txt file need to be adjusted to recognize and take into account the weapon and ammo weight. BAR, Bren, MG34 and other heavy weapons, crew served or not, need to have the Weight column reduced by a reasonable amount. Make him put down the rations, canteen, entrenching tool. extra socks and that 297 1/2 feet of hemp rope that he smokes when no one is looking.
Others have said that the way to go would be to increase the other weapon combos in the Soldier.txt file, but that not only denies reality, it produces one massive load of additional weaps lines that have various kit weight load outs to account for riflemen that are or are not part of a team with a heavier weapon. Another approach would be to add some calculation to the .exe to balance the load out of a team with a heavy support weapon to equalize the load across all members, but then you would also need to be able to reduce the ammo if one of the team gets potted along the way.
The easiest and best way is to reduce the Weight of the kit for those sprites assigned a heavy support weapon. They then do stay with the rest of the team, more or less, depending on incoming fire and will sometimes even be the first to arrive at the move waypoint.
C'est magnifique, mais ce n'est pas la guerre.
