A jury fоund Juan Martinez and Jorge Cardenaz guilty of conspiracy to possess, and possession of, marijuana with intent to distribute. See 21 U.S.C. §§ 846, 841(a)(1). The indictment specifically alleged that both the conspiracy and the substantive violation involved at least 1,000 kilograms of marijuana, a quantity that would trigger a statutory maximum of life imprisonment instead of the default maximum of five years. See id. § 841(b)(1)(A)(vii), (b)(1)(D). The jury was not asked to make a specific finding as to drug quantity but instead was told, apparently without objection from the defendants, that in order to convict on either count it had to find that the government proved the amount alleged in the indictment. Later at sentencing the district court concluded that the precise quantity equaled 1,407 kilograms, and used that figure in applying the sentencing guidelines. The court sentenced Martinez to 126 months’ imprisonment, but assessed Cardenаz three extra offense levels as a manager or supervisor of the conspiracy and sentenced him to 210 months. On appeal Martinez and Cardenaz contend that their convictions must be set aside because no rational jury could have found beyond a reasonable doubt that the charged offenses involved at least 1,000 kilograms of marijuana. Both appellants also contend that the jury, rather than the district court, should have decided the drug quantity used in applying the sentencing guidelines, and that the district court overstated thе relevant amount. Finally, Cardenaz objects to the upward adjustment in offense level for his leadership role. For the reasons that follow, we affirm the convictions and sentences of both appellants.
I.
In December 2004 authorities learned through wiretaps that a large quantity of marijuana would be delivered to the residence of Hector Torres in Indianapolis, Indiana. Federal and state investigators set up surveillance at the residence, and on December 13 they witnessed the arrival of Carlos Pelayo-Guzman, the buyer frоm Chicago, Illinois, who was to take delivery of the incoming marijuana at Torres’s home. After roughly half an hour, Torres and Pelayo-Guzman left together in the latter’s Jeep and drove to a nearby parking lot, where they met appellant Carde-naz and a fourth man, Elvis Garсia.
Meanwhile, what the surveillance team did not yet know was that appellant Martinez and Johnny Gutierrez were waiting across the street in a white Ford van disguised with FedEx logos. The two had driven the van and its cargo of marijuana-laden crates from Indianapolis to Houston, Tеxas. Cardenaz pointed out the van to Torres and Pelayo-Guzman and then joined them in the Jeep. The three departed for Torres’s house, followed by Martinez and Gutierrez in the van. Garcia stayed behind at the parking lot. When they reached Torres’s home, Martinez backed the van carrying the drugs up the driveway and partway into the garage.
Surveillance officers had lost the Jeep in traffic, but one of the investigators returned to Torres’s residence and saw Martinez and Gutierrez exit the FedEx van and begin unloading it with help from the others. Fiftеen minutes later, uniformed state police officers approached the open garage from the sidewalk and saw bales of marijuana stacked on the floor. Martinez, Cardenaz, Torres, and Pelayo-Guzman were all in the garage. Torres was the first to sрot the officers; he immediately *508 yelled, “Police!” and ran into the house. The others were ordered not to move, but only Cardenaz complied. Martinez and Pelayo-Guzman followed Torres from the attached garage into the adjoining family room, but were quickly caught after exiting through the back door. Gutierrez was found hiding in a closet, and Garcia was picked up separately. Fourteen bales of marijuana were recovered from the garage floor; seventy more were found in the family room, and another 118 were still in their crates in the van.
Torres, Pelayo-Guzman, Gutierrez, and Garcia all pleaded guilty to the conspiracy count and testified for the government at Martinez and Cardenaz’s joint trial. Torres testified that he, along with Pelayo-Guzman and Cardenaz, traveled in the Jeep to his home on the night of December 13, with the FedEx van following. According to Torres, Cardenaz used a cellular phone to communicate with the occupants of the van, Martinez and Gutierrez, during the drive. Torres testified that once they arrived at his house, he parked in the street, while Martinez backed the van into the garage. After Martinez unlocked the doors, Torres, Pelayo-Guzman, and Carde-naz unloaded the crates of marijuana by “assembly line”: Cardenaz removed the marijuana bales from the van and handed them to Pelayo-Guzman, who handed them to Torres, who carried them into the family room. According to Torres, Martinez stood next to him in the garage counting the bales, while Gutierrez, who was ill, had gone into the house to watch television. Pelayo-Guzman confirmed that Martinez counted the bales as they were removed by Cardenaz and passed them to him and on to Torres. Gutierrez added that Garcia’s uncle, Jorge Garcia, had hired him to transport the marijuana with Martinez from Houston to Indianapolis. And, finally, Garcia recounted that his uncle had asked him to drive behind the FedEx van from Houston to Indianapolis to “oversee the drop.” Garcia testified that Cardenaz accompanied him in the car, in part, because Cardenaz had an “ownership interest” in the marijuana. Martinez and Car-denaz, who stipulated that the net weight of the marijuana found at Torres’s residence exceeded 1,000 kilograms, argued that the government’s evidence showed only that they were present during a drug transaction. Neither presented any evidence at trial.
After trial a probation officer prepared presentence reports for Martinez and Cardenaz. The officer reported that the total amount of marijuana recovered from the van, garage, and family room was roughly 1,400 kilograms, though any amount from 1,000 to 3,000 kilograms would have yielded the same base offense level of 32. See U.S.S.G. § 2D1.1(c)(4). Martinez received no offense-level adjustments and had no criminal history; therefore, he faced a guidelines imprisonment range of 121 to 151 months. Cardenaz’s offense level initially was calculated at 32 as well, but the government argued over his objection that Cardenаz was a leader in the conspiracy and should receive a four-level increase. See U.S.S.G. § 3B1.1(a). At sentencing the government highlighted Garcia’s testimony at trial that Cardenaz was an overseer of the operation. The government also emphasized, and Cardenaz conceded, that various conspirators had asserted during interviews with investigators that Car-denaz helped plan the marijuana delivery. The district court agreed with the government that Cardenaz served a supervisory role, but because the evidence suggested that Jorgе Garcia was the principal leader of the conspiracy, it increased Cardenaz’s offense level by just three as a manager or supervisor instead of giving him a four-level increase as an organizer or leader. See U.S.S.G. § 3Bl.l(b). Cardenaz’s crim *509 inal history category was III, which resulted in а guidelines imprisonment range of 210 to 262 months. The district court sentenced both defendants toward the low end of their respective ranges.
II.
On appeal Martinez and Carde-naz first argue that the evidence is insufficient to support their convictions for conspiracy to possess and possession of marijuana. We have repeatedly noted that defendants challenging the sufficiency of the evidence face a high burden.
See, e.g., United States v. Emerson,
In this case, Martinez and Car-denaz seek to overturn their
convictions
because, they contend, a rational jury could not have found that the marijuana bales in the family room were part of the shipment delivered in the FedEx van, and thus could not reasonably have concluded that their drug offenses involved at least 1,000 kilograms of marijuana. This contention incorrectly presupposes that drug quantity is an element of the charged offenses. As we have said repeatedly, the drug quantity is not an element of the crimes defined by § 846 or § 841(a)(1).
See, e.g., United States v. Tolliver,
Inviting our attention to the Supreme Court’s decision in
Cunningham v. California,
Martinez and Cardenaz also argue that, at sentencing, the district court failed to consider whether the entire load of marijuana was reasonably foreseeаble to them. The court did not, in fact, consider foreseeability, but neither was it required to. Under the sentencing guidelines, a defendant in a drug case is liable for any amount that he was directly involved with, as well as any amount attributable to his coconspirators, so long as the additional amount was reasonably foreseeable to him.
See
U.S.S.G. § 1B1.3(a);
Hollins,
Finally, Cardenaz argues that the district court improperly increased his offense level after finding that he was a managеr or supervisor in the conspiracy.
See
U.S.S.G. § 3Bl.l(b). We review the district court’s determination of a defendant’s role in the offense for clear error.

Notes
. The government proposed to submit a special verdict to the jurors, asking them to decide the weight of the marijuana. This was the proper means of seeking a jury determination on the question of drug quantity.
