you know you've played Battlefield too much when....

you start opening doors and windows with a knife

you walk past a boarded up house and wish you had a knife with you because your sure the second floor would be a good sniper spot

you wonder why the garden furniture doesn't break into pieces when you walk into it.

pointing your mobile phone at a building doesn't give anyone co-ordinates for a mortar strike

walking down a road you see a triangular red road sign (probably dont have them in the USA im in UK) and assume a crate is nearby and you start looking for it in hope it contains nothing but gold bars

walking past a market stall you hear the market trader shout "how you like them apples?" you immediately run for cover

a pair of binoculars does nothing to guide a rocket to blow up a vehicle

you realise a medikit doesn't instantly heal any wounds or injuries you have

you find a rucksack on the ground and after looking through it realise it doesn't contain any weapons or gadgets to take out tanks
