Four things to know about medkits to truly be credit to team:
1) Medics always get first dibs on medkits
If there’s a Medic nearby, go to him for heals instead of medkits. Being the top target for the enemy team, he’s most likely going to need health or a quick extinguishing in due time. It’s better to let him have something to fall back on, than have your team suffer the disadvantages and respawn time of a dead medic.
2) Before grabbing a medkit, look and see if anyone else needs it more
If you’re just topping off your health, or not on fire, let your near-death, on-fire, or bleeding teammates take the health before you. They probably won’t survive the time it takes for medkits to respawn if you take it for yourself.
3) Heavies can drop their sandvitch with alt-fire, (Right-click) which acts as a medium-medkit for other players
Your sandvitch isn’t just for you, it can also save the life of dying teammates. All medics love a Heavy considerate enough to share a sandvitch and save them from burning or dying. However, you yourself can’t benefit from this. If you pick up your own dropped sandvitch, you’ll just recharge your food meter.
4) Heavies can fully recharge their food meter by picking up a medkit at full health
This works with any size of medkit. You can use this to “upgrade” a small medkit to a medium-sized one for your teammates, or essentially take the medkit with you for later, so your teammates don’t have to retreat for health.
