The hull and turret are made of a high-strength aluminum alloy, with the front of the hull being provided with an extra steel plate welded over it plus spaced armor from the trim vane. The turret is also provided with a thick steel spaced armour shield over its frontal arc. Over the frontal arc, the vehicle is protected against 30&nbsp;mm gun rounds at a range of 200&nbsp;m.<ref name="znamia.ru">{{cite web|url=http://www.znamia.ru/produkciya1/primenenie_agregatov_proizvodimyh_i_remontiruemyh_na_oao_mmz_znamya1/military/boevaya_mashina_pehoty_bmp_3/ |title=Боевая машина пехоты БМП-3.

It is specially constructed to act as armour, effective against shaped charge warheads as well as any autocannon shells that managed to go through the front armour.

The BMP-3 can create a smoke screen by injecting fuel into the exhaust manifolds.<ref>{{cite web |author=ARG |url=http://www.military-today.com/apc/bmp_3.htm |title=BMP-3 Infantry Fighting Vehicle |publisher=Military-Today.com |access-date=2010-08-24 |archive-url=https://web.archive.org/web/20090819075336/http://www.military-today.com/apc/bmp_3.htm |archive-date=2009-08-19 |url-status=usurped }}</ref><ref>{{cite web |url=http://www.historyofwar.org/articles/weapons_bmp3.html |title=BMP-3 Infantry Fighting Vehicle (Russia) |publisher=Historyofwar.org |access-date=2010-08-24 |archive-url=https://web.archive.org/web/20100621015745/http://historyofwar.org/articles/weapons_bmp3.html |archive-date=2010-06-21 |url-status=live }}</ref> A chemical agent detector, an FVU filtration system, an automatic fire extinguisher and six 902V "Tucha-2" 81&nbsp;mm smoke grenade launchers are standard.

At least two distinct sets of explosive [[reactive armour]] kit are currently available, giving the BMP-3 protection from less advanced rocket propelled grenades. One of them is the Kaktus ERA kit, which has a unique design that creates minimal acoustic and kinetic backlash to the armour behind it upon detonation, thus ensuring that the occupants will not be harmed by shockwaves from the ERA block. The ERA blocks will completely disintegrate after detonation. According to Kurganmashzavod, the BMP-3 may also be fitted with additional side armor tiles, which can resist .50 caliber armour-piercing ammunition perpendicularly at close ranges. They give the BMP-3 added side protection from autocannon fire as well. BMP-3s serial production with ERA started as of November 2022.<ref>{{cite web | url=https://armstrade.org/includes/periodics/news/2022/1111/161570334/detail.shtml | title=ЦАМТО / / В России начался серийный выпуск БМП-3 с динамической защитой }}</ref>

The BMP-3 also has the ability to carry a [[Shtora-1]] electro-optical jammer that disrupts semiautomatic command to line of sight (SACLOS) antitank guided missiles, laser rangefinders and target designators. Shtora is a soft-kill, or passive-countermeasure system. BMP-3s serial production with the [[Nakidka]] camouflage system started as of May 2024.<ref>{{cite web | last=Новости | first=РИА | title=Партию улучшенных по опыту СВО БМП-3 досрочно поставили Минобороны | website=РИА Новости | date=2024-05-07 | url=https://ria.ru/20240507/bmp-1944290604.html | language=ru | access-date=2024-05-08}}</ref> BMP-3 infantry combat vehicles started receiving serially outfitted drone suppression systems in June 2024.<ref>{{cite web | title=БМП-3 получили штатную защиту от дронов | website=Центральный Военно-Морской Портал | date=2024-06-24 | url=https://flot.com/2024/%D0%9C%D0%B2%D0%BC%D1%8120/ | language=ru | ref={{sfnref | Центральный Военно-Морской Портал | 2024}} | access-date=2024-06-25}}</ref>

The standard weight of the vehicle is 18.7 tonnes. If additional armour overlay (metal sheet of armour and Kaktus ERA) is installed, the weight will reach to 22.2 tonnes. The body is covered from the sides and the top. In such kit, it is protected against 12.7&nbsp;mm machine gun rounds in the range of 100–200&nbsp;m.<ref name="znamia.ru" /> [[Rostec]] reported in September 2023 that the production of additional protection kits for the BMP-3 increased 30 times in comparison with 2022.<ref>{{cite web | url=https://armstrade.org/includes/periodics/news/2023/0908/091075152/detail.shtml | title=ЦАМТО / / «Ростех»: выпуск комплектов дополнительной защиты для БМП-3 вырос в 30 раз по сравнению с 2022 годом }}</ref>
