How to unlock the Recon achievement in Battlefield 4 - Definitive Guide
You can also use this playlist as you go through the game:
A YouTuber by the name of HarryNinetyFour has a series of videos that show the location of ALL the collectibles in each mission. *below*
*NOTE: If you are going for the "Full Arsenal" Trophy, you have to obtain all of the collectibles, even though this trophy only requires 28 of them. (There are 35 in total)
You can also use this playlist as you go through the game:
Although the trophy description says to find 28 collectibles, you will still want to find all 35, as they are required to unlock Full arsenal. The collectibles consist of weapons and dog tags, and they are saved after you pick them up. Thus, there is no need to collect them again if you die, restart a checkpoint, or exit a mission. Pressing during a mission will allow you to view your progress toward the collectibles in that mission. You will unlock all previous collectibles trophies en route to this one.
You can view the Collectibles Guide written by Harry94_, complete with images and videos, or simply watch his videos below to easily find all 35 collectibles. You are able to pick up the weapons of fallen enemies, which may enable you to unlock this trophy (and previous collectibles trophies) prior to reaching the 28th collectible in the guide. This is very likely to happen, but remember to continue finding collectibles until you have obtained all 35.
To make things easier, here is one general video on collecting all the weapons and dog tags.
And here is a video for each mission separately :
