i would suggest that once the initial find is done that subsequent rearms are shorter.
currently it is like this....( imagine you are doing it for real)
get to the crate, look inside to find what you need then supply with one patch,round,grenade.
then start the whole process from look inside again.
surely once you have located what you need from the crate you would not have to spend time looking for it again.
i suggest using the grenadier as example;
get to the crate, than the timer starts maybe 25 seconds to find the grenades within the crate, then 5 seconds to take each round that you need.
then if you need another item, lets say a patch, you have to find it in the crate again, 25 seconds.
maybe the engine won't allow this but its well worth a try
