Infantry Survivability

[Imp]

Firstly arty, seems about right to me there are some very nasty pieces to choose from. Dont expext instant results but even against dug in units 5 turns worth kills stuff. Thats 15 minutes of bombardment which is nothing look at what proceeded a major attack in WW2 several hours is common. Arty is not an instant kill nor is that its main goal in most cases & most people play with 10% restriction. How about a Russian attack in WW2 with 1 gun per hex front (80 high = 80 guns) all you do for the first 20 turns is bombard & send scouts observers. Now the arty has done something you cant get anybody to do anything which is why we tend to go for 10% or so.
Vehicle based weapons vs troops
Chainguns/ autocannons are leathal more so I would say than main guns.
Main guns often kill the odd unit at 300m or less but more importantly can often suppress the unit. Vs crewed weapons they are leathal even something like a WW2 low calibre weapon can kill a gun or MG crew with one hit. The reason for this I think is the crew is a grouped target so one shell if it lands near hits everyone. The squad on the other hand sees the tank & spreads out in its 50m hex for protection, even a well placed shell would then only inflict 2-3 casulties. He may be a grunt but hes not stupid spreading out cuts losses & increases the chance of someone sneaking up.
Think about it how often even on a long shot have you killed an ATGM outright. I do it all the time infantry engage him drawing shots or arty pins & post 80s tank moves 1 hex & kills at 1-2km. 3 tanks stand a good chance of at least taking him out of the action if not killing outright.
Vehicle MGs in MBT are to effective, I think this is because FC giro etc apply to ALL weapons not just the maingun but this is how the game is programed.
As a note not sure here but you tend to use Main Guns as prep fire before your infantry opens up. If fire instead at routing units I am pretty sure they are no longer considered dispersed & killing 4 men a hit is not uncommon. This is also when MGs work well get a group clumped running in the open & MGs will massacre them. 2 tanks spreading the love to keep them running can easily wipe out an entire routed Inf Co in a few turns if the ammo lasts, though a couple of squads in tow as eyes is advisable
