Metal Gear Solid 4: Guns of the Patriots Tips

this is just fun not really a cheat persay
I just found this out last night and I did not know this, it maybe is common knowledge among Mgs4 players. You can strap c4 to the backs of militiamen or pmcs and let them walk away then detonate. It helps to have stealth equiped and just sneak up behind them and plant the c4. This tip is really just fun to do its not really helpful but nevertheless I thought I would share anyway
