I asked 2015 about the garand relaod and emagoo responeded with this
"As for reloading half-way through, we originally had it so you couldn't eject the clip before it was empty, but that was really pissing everybody off here

. So we enabled the reload for that weapon (you're assessment was correct, done for gameplay reasons

."
As for the reload being quick i said this on the dod forums so ill say it here
"Say for example you were on seg 3 in dod and had 2 rounds left in the garand and 5 germans were running down the hill. U have 3 options fire your shots and attempt to reload, fire your shots then try to kill em with the pistol (very unlikely) or run away somewhere and reload and come back to fight.
In medal of honour at least you can reload quickly and fight. Anyone that has a garand could probably say how long it would take to reload and i would say it can be done by a lot of people in 2 seconds or maybe less.
A lot of people on this forum say sometimes realism has to be sacraficed for fun and personally i like the way the garand reload is implemented in moh. Its fast and efficient,you dont have to wait for the bandolier to pop out and only takes about 2 seconds to reload compared to 5 or 6 seconds in dod."
